In the autumn of September, when the white dew arrives one after another, most of the country begins to change from hot to cool. This is the month of the transition between summer and autumn, and it is also a critical period for crop growth. With the arrival of white dew, the cold air of the northern plateau gradually takes over, the warm air is forced back, and the water vapor condenses on the grass and trees at night to form dew. At the autumn equinox, the direct point of the sun moves to the south, the days gradually become shorter, the temperature gradually drops, the temperature difference between day and night increases, and late autumn has arrived.
At this time, the days are short and the nights are long, the cooling accelerates, and the autumn harvest, autumn ploughing and autumn planting become particularly intense and compact. If you are not careful, you will miss the agricultural time. In order not to delay the farming season and improve the planting efficiency, I will share the delicious and well-planted vegetables that are suitable for planting after the white dew. As long as you grow these vegetables, you won't have to worry about running out of fresh vegetables in autumn and winter.
The first vegetable is coriander. Coriander is a versatile vegetable that can be grown from late August to mid-September. It only takes ten days after sowing to pick and eat. When planting coriander, you need to pay attention to the following points: choose fields with fertile soil, strong water retention capacity and good drainage conditions for planting, and avoid heavy planting, so as not to cause large-scale pests and diseases. Fertilization management should be reasonable, according to the standard of 1,000 catties per mu of basal fertilizer deep application to the field, and watering the bottom of the water, so that the soil is kept moist, and water and fertilizer are fully integrated. Due to the short growth cycle of coriander, the amount of fertilizer required is small, and there is no need for top dressing when the bottom fertilizer is sufficient. If the base fertilizer is insufficient and the growth of coriander is poor, some urea can be applied appropriately with water to help restore its growth state. Finally, sowing management should pay attention to sprinkling the coriander seeds soaked and sprouted in advance into the leveled soil, and then cover the film to keep warm and moisturize. In general, the seedlings can emerge in seven days, at which point the film can be removed. However, it should be noted that too high a temperature will cause the plant to turn yellow and wilt. When the height of the plant reaches 10 to 10 centimeters, it can be picked, and after picking, it can be topdressed to promote plant growth. It should be noted that the harvesting period of coriander can last until the next year. If the temperature is too low during the period, it is necessary to cover the seedlings with straw or haystacks to protect the seedlings from wintering to prolong the harvesting period.
The first vegetable is spinach. Spinach is suitable for planting in September and can be harvested 10 to 10 days after planting. The harvest time is generally between the end of *** and the following month. Planting spinach needs to pay attention to the following points, choose varieties with heat resistance, strong stress resistance, and early maturity for planting, and avoid choosing varieties with poor heat tolerance, susceptibility to pests and diseases, and long maturity cycle. Before sowing, soak the seeds in warm water to promote germination, and when the seeds are exposed to white germination, they can be sown in fertile fields with strong water retention capacity. You can also gently rub the seeds directly into the soil and lightly cover the soil to keep the soil moist. Thirdly, water and fertilizer management should be reasonable. The base fertilizer is mainly rotted farmhouse fertilizer, and the amount of fertilizer should be appropriately large, too small will lead to premature spinach mossing. In the case of sufficient fertilizer, the yield is more guaranteed, but it is also necessary to be vigilant against excessive fertilizer consumption, which leads to vigorous seedling burning. Finally, when the plant grows to 10 to 10 centimeters, it is appropriate to pick up large seedlings for harvesting, and it can be harvested twice or twice. To top dressing after harvesting, you can use fast-acting nitrogen fertilizer to spray it on the spinach so that the spinach can better absorb nutrients.
The first vegetable is turnips. Radish is suitable for planting at the end of August and early September, and the plant can be harvested after two months of growth. When planting radish, you need to pay attention to the following points: choose loose soil and nutritious fields for planting, and avoid continuous cropping with cruciferous vegetables, so as not to increase the probability of outbreak of pests and diseases in the field. At the same time, it is suitable for continuous cropping with eggplant beans and melon crops. The field should have good drainage and irrigation conditions, and the soil should be leveled with a rake, and the soil lumps in the field should be broken to make the field smooth and loose, and the ability to retain water and fertilizer should be enhanced. Again, it is very important to sow seeds at the right time. Before sowing, it is necessary to ensure that the soil has moisture, if the moisture is not good, you can first carry out flood irrigation and water replenishment, and then level the soil for sowing, so as to ensure that the seedlings can grow in the temperature range of 10 to 10 degrees Celsius. Fertilization and weeding are also indispensable. Before planting, the soil should be deeply cultivated, manure should be applied according to the standard of 1,000 to 1,000 per mu, and 100 catties of plant ash and 10 catties of superphosphate should be applied. In the whole management process, it is necessary to adhere to the principle that grass must be hoeed, and avoid grass and radish competing for water, fertilizer and sunlight; At the same time, it is also necessary to adhere to the principle of hoeing after watering and hoeing after rain, because this stage is a critical period for weeds to obtain water and grow rapidly, so we must hoe weeds in advance. Finally, watering management should be carried out in stages according to the growth situation, and the amount of water should be controlled too much at the seedling stage to prevent the plant from growing; From the belly breaking period to the shoulder-baring stage, the ground can be whitened and dried before watering; During the growing season, the soil should be kept moist but not short of water to prevent the occurrence of chaff. If the soil is too dry, you can rehydrate it on a two-week cycle.
The first vegetable is cabbage. Cabbage has a wide planting area, high yield, storage and transportation resistance, and is cheap and economical, and is popular among consumers. When planting cabbage, it is necessary to pay attention to the following points: choose fields with strong soil permeability and coordinated water and fertilizer ratio for planting to improve the disease resistance and stress resistance of crops. Therefore, when planting cabbage, it is necessary to avoid crop rotation with similar crops to ensure good drainage and irrigation conditions to ensure the effect of drought irrigation and flood drainage. Adequate basal fertilizer application is the basis for high yields. The amount of basal fertilizer should be sufficient to provide sufficient nutrients for the plant to support its healthy growth, and the difficulty of topdressing operation in the later stage will be greatly reduced. For cabbage fields, the amount of basal fertilizer should be applied according to the standard of 1,000 to 1,000 kilograms per mu, and with ten catties of compound fertilizer, these fertilizers should be evenly and deeply applied to the soil, so that they can produce fertilizer effects for a long time. Top dressing irrigation is also a very important link, need to keep in mind the principle of light and heavy supplement, that is, light chasing seedling fertilizer, clever top dressing tree fertilizer, heavy chasing core fertilizer, top dressing core fertilizer, top dressing core fertilizer, the specific type of top dressing and the amount of fertilizer should be adjusted according to the specific situation to meet the growth needs of plants. In terms of irrigation, the key period mainly includes the seedling stage, which should keep the soil relatively moist; During the rosette stage, water should be replenished according to the growth of the plant, weather and moisture; Adequate watering should be done in the early stage of the balling stage, and the frequency of irrigation should be reduced in the later stage to prevent overwatering from causing adverse effects on the plants. Finally, it should be noted that as the growth temperature of the plants continues to decrease, it is necessary to pay attention to warm and cold-proof measures, such as building windproof shelters or using straw straw to keep warm, etc., to protect the plants from frost damage. As long as the cabbage meets the standards, it should be harvested sooner rather than later to avoid the risk of frost damage and affect the improvement of yield and quality.
In short, planting vegetables seems complicated, but in fact it is simple, as long as the management process can be standardized, the management details can be refined, the goal of high-quality management can be achieved, the yield and quality can be improved, and people will be provided with more and better fresh vegetables, to meet their needs, but also to promote the development of agriculture and economic growth, for the benefit of the public.
