The day is the sowing season, some vegetables are planted in spring and harvested in summer and autumn, while some vegetables can be harvested in spring and spring. When the spring planting time is warmer, when the ground temperature reaches more than 10 degrees Celsius in 5 cm, you can generally start to prepare to plant some cold-resistant lettuce in mid-March to make up for the lack of market **. The several vegetables introduced in this article are simple to grow, less diseased, and can be harvested every month
1. Lettuce. There are many varieties of lettuce, and the varieties with high yield and good reputation are Italian lettuce, glass lettuce, and cream lettuce. Lettuce is planted in the open field with good quality, good taste, and beautiful plant shape, especially suitable for garden cultivation. Planters should be fertilized to meet the nutrient needs of the lettuce. Lettuce is mainly sown, not too dense, after the emergence of seedlings should also pay attention to the seedlings, can also be transplanted, although the growth period is longer after transplanting, the plant grows big and good. In addition, the growth needs more water, and the soil should be kept moist frequently, but it should be watered lightly with small water, and it is not suitable to water with large water.
2. Oily wheat cabbage.
Oilseed wheat is also one of the leafy vegetables, the root system of the plant is developed, suitable for fertile, water and fertilizer retention strong soil, the same before sowing to apply foot fertilizer, and organic fertilizer, less chemical fertilizer. Organic fertilizer can be applied about 4 square meters per mu, and the whole growth period of chemical fertilizer urea shall not exceed 20 catties per mu, so as not to exceed the nitrate of vegetable leaves. Rapeseed live broadcast is good, sowing should be soaked first and then sown, covering the soil should not be too deep to 05 cm as well. After budding, spray to moisten, do not pour large water. Top dressing 1 2 times during growth to promote leaf growth.
3. Shanghai green.
Shanghai green, with thick leaves, good taste, and purple leaves. The key to planting Shanghai greens is to choose high-quality varieties, followed by sufficient base fertilizer, and finally the density is appropriate, and the planting is as thin as possible. If it's too dense, it will grow slender and long, and it won't taste very good. Shanghai Qingduo adopts the seedling transplanting method to improve the yield and quality. In order to improve the taste, more organic fertilizer should be applied in fertilization, and not less than 80 catties of cake fertilizer per mu, and functional fertilizer should be used as top dressing, less simple fertilizer should be used, and compound fertilizer should be better.
In terms of pest control, pesticides are not used, and soil methods are used to control pests and diseases to ensure the safety of dishes.
4. Baby cabbage.
There are many varieties of bok choy, such as;Jingyan Kuaicai No. 2, Kuaicai 539, Yangtze River No. 6, etc. These vegetables are real fast lettuce, harvested twenty days after sowing, and can be planted with multiple crops throughout the spring. Apply organic fertilizer as the base fertilizer before each sowing, and apply enough nitrogen fertilizer, do not top dressing during the growth process, and keep the soil moist when watering. Generally, 5 square meters of high-quality soil miscellaneous fertilizer are applied per mu, and urea is used for chemical fertilizer, 30 kg per mu, or 60 kg of compound fertilizer. If the yellowing of the leaves during the growth period is mostly caused by lack of fertilizer, you can apply foliar fertilizer, spray 1 urea aqueous solution, or apply amino acid fertilizer with water.
5. Cabbage. Rapeseed, also known as cabbage, grows about the same size as bok choy, after sowing.
It can be harvested in 40 or 50 days. The main edible part of the cabbage sum is the flower sprout, which is characterized by being cold and heat resistant, can be sown in mid-March, the seeds germinate at 4 degrees, and the maximum temperature must not exceed 30 degrees. This vegetable should be transplanted with seedlings, which can be thinned to facilitate the growth of moss. Keep the soil dry and wet in the early stage of growth, so that the plant grows vigorously, and the later stage is appropriately drought to promote flowering. When the main sprout is equal to the height of the leaves, and the flower buds are beginning to bloom, it is a suitable harvest period, and the taste is poor when the harvest is late.
6. Cherry radish.
Cherry radish is a fleshy root vegetable, but the bulging flesh is very small, and the seedlings emerge two or three days after sowing, and the fleshy roots begin to expand about 15 days after the seedlings emerge, and it takes about 30 days from planting to harvesting.
During the growth of cherry radish, the temperature should be controlled between 8 and 24 degrees, the suitable temperature is about 20 degrees, and the suitable temperature for seed germination is about 22 degrees. The optimum temperature for growing is between 15 and 25 degrees Celsius, and can be planted in all seasons except winter.
It should be noted that the planting ground should be loose and fertile, and it should be deeply cultivated and raked before planting to create a good soil environment for root growth. When the fleshy roots are enlarged, it is necessary to maintain uniform and moist soil moisture, and the taste will be crisp and tender.
7. Artemisia chrysanthemum.
The suitable temperature for the growth of chrysanthemum is 15 to 20 degrees, and the light requirements are not strict, especially suitable for growing in the cold environment of early spring. Artemisia chrysanthemum seeds absorb water slowly and are not easy to germinate, so they should be soaked and germinated when sowing, and then sown. This vegetable grows quickly after emergence, and can be harvested successively 45 days after sowing. Artemisia chrysanthemum is divided into large and small leaf varieties, and the small-leaf varieties are heat-resistant, so the spring varieties are mainly small-leaved chrysanthemum, and the fragrance is stronger.
8. Fennel seedlings.
Cumin is a seasoning vegetable, and fennel seeds emerge slowly, and the seedlings emerge about a week after sowing, so they should be soaked and germinated before sowing. Keep the soil moist after the emergence of seedlings, use the method of light watering with small water, when the plant is 20 cm high, it can reduce the number of watering, promote the root system to take root, and the plant can be harvested successively when it grows to more than 30 cm. The plant is fluffy and occupies a large space for growth, so if you want fennel to grow well, it is not easy to plant too densely, and you can also properly spacing the seedlings after emergence, so that the plant spacing is 8 10 cm.
