It is common sense to water and fertilize vegetables when growing them. But there are also some people who are always worried about watering and don't know which vegetables need how much water and when to water them. This article will introduce you to the characteristics of commonly planted vegetables that like water or are afraid of water, and help you water them correctly.
1. Nightshade vegetables.
1. Eggplant: The requirement for water for growth is that the soil is moist and the hand does not run water.
Eggplant likes water and is afraid of waterlogging, because of its lush branches and leaves, large transpiration and water demand, it is good to hold 80% of the water in the soil field during the growth period, and the relative humidity of the air is 70% 80%. If the humidity is too high, the disease is serious, especially the soil is waterlogged, which is easy to cause the roots to die. Eggplant has a well-developed root system, which is more resistant to drought, especially before fruit setting, properly controlling water and keeping the soil moist, and it is necessary to carry out multiple tillage to promote root development, prevent seedlings from growing, and facilitate flower bud differentiation and fruit setting.
Eggplant enters the fruiting stage due to its large leaves, lush branches and leaves, and strong transpiration, which requires sufficient soil moisture. It is necessary to take light watering with small water, and it is not suitable to cause water accumulation in the field. When there is a lack of water, the plant grows poorly, the quality of the flowers is poor, and the flowers are mostly short, and the fruits are small and dull. Therefore, the method of pouring when dry is adopted.
2. Tomato: It is also a water-loving vegetable, due to the developed root system of tomato, strong absorption capacity, and lush stems and leaves, strong transpiration, and more water demand. However, it does not require a lot of irrigation, especially in the seedling stage and early flowering stage, and if the water is too much, the seedlings will grow and the fruit will be affected. The amount of watering should be sufficient during the fruiting period, and 60% to 80% of the soil moisture content should be maintained. If the soil moisture is too high and the drainage is poor, it will affect the normal respiration of the root system, and in severe cases, the roots will rot and the seedlings will die. In addition, the soil should be kept moist during the fruiting period, such as the soil is dry and wet, especially after drought, it is easy to have a large number of fruit cracks and induce umbilical rot. The general watering of tomatoes is to water lightly with small water for flowering, mainly to control water and promote root growth. After fruiting, increase the amount of watering but should not flood irrigation, so as not to cause water accumulation, produce roots, adopt the watering principle of seeing dry and wet, and always keep the soil moist.
3. The root system of pepper is shallow and underdeveloped, so the demand for water is not very large, so pepper is neither drought nor waterlogging, and the quality of water management is the key to obtaining high yield.
In a growth and development period of pepper, although the water demand of pepper gradually increases after planting, the soil should not be too wet in the early stage, and the seedlings should be squatted appropriately to promote the growth of pepper roots and flower bud differentiation.
The water demand of the plant increases at the early flowering stage, and a large amount of water can be supplied at this time to meet the needs of pepper flowering and branching.
In the fruit expansion period, it is the peak period of pepper water demand, and the appropriate amount of water should be ensuredIf there is too little watering, the fruit will swell slowly, dull and dull, and it is easy to appear deformed fruits.
The amount of watering also affects the air humidity, the suitable air relative humidity of pepper is about 70%, and too high humidity can easily affect pollination, causing flower drop and disease. It can be seen that reasonable moisture** is important for the high yield of peppers.
4. Beans: Beans have a relatively developed root system, stretching far to the surroundings and rooting down deeply, so the ability to absorb fertilizer and water is relatively strong, so the beans have a certain drought tolerance. Especially in the seedling stage of carob, the plant is relatively small, the amount of water needed is less, not too much water, it grows well in a humid environment, but the ability to tolerate waterlogging is poor, the demand for water in each growth period is not balanced, and too much water in the seedling stage often causes the growth of long carob to be too vigorous, resulting in a decrease in pod setting rate, so reasonable watering, combined with the watering characteristics of carob in different periods of watering, is conducive to the growth of carob.
5. Cucumber: Cucumber likes moisture, is afraid of waterlogging, is not drought tolerant, and is sensitive to moisture, and is more strict with soil moisture and air humidity. The suitable soil moisture of cucumber is 60% to 90% of the soil water holding capacity, 60% to 70% at the seedling stage, and 80% to 90% at the adult stage. Seedling stage and early flowering stage. The water requirement at this stage is relatively weak, and it is necessary to properly control the water ** to prevent the seedlings from growing wildly and rooting. Fruiting period. This stage is the period when the vegetative growth and reproductive growth of cucumbers are synchronized, and the water consumption is large, so it should be watered in time, and it is better to water with small water.
2. Leafy vegetables.
1., garlic seedlings: The fibrous roots of cabbage are shallow in the soil, which is a vegetable that is not water-tolerant and drought-tolerant, and has low requirements for soil moisture. Too much water can easily cause garlic seedlings to rot their roots, affecting their growth. Generally, there is no need to water at the seedling stage, and you can water it after pulling out the garlic moss to promote the expansion of the garlic.
2. Leek: Leek is a vegetable that does not require much water. The roots of leeks are relatively well developed and are not adapted to too much water. Therefore, it is necessary to pay attention to the appropriate amount of watering and avoid stagnant water. Leeks have shallow root systems, underdeveloped root hairs, and weak absorption capacity, so they like moisture and are afraid of waterlogging. Moisture requirements vary depending on the growth period. When the seeds germinate, the relative moisture content of the soil needs to reach 70%-75%, so that the seeds can smoothly absorb water and expandThe water absorption capacity of the root system at the seedling stage is weak, and the relative water content of the soil is required to reach about 70%.The water absorption of the product is large during the formation period, and the relative moisture content of the soil should reach 80% and 85%. The leaves of leeks are narrow, smooth, waxy, showing the characteristics of drought tolerance, so low air humidity is required, and diseases are easy to occur when the relative humidity is too large, so it should be kept at 60% 70%.
3. Cabbage: The root distribution of cabbage is shallow, the leaves are large, and the transpiration is vigorous, which requires growth in humid climate conditions and is not drought tolerant. The seedling stage requires less water, and the squatting seedlings are mainly controlled by water to promote the root system. The need for water increases from the rosette stage, increasing the frequency of watering to keep the soil moist. The water requirement is gradually reduced after the coring, and the water is stopped 10 days before harvest to avoid cracking the balls.
4. Small greens.
Small green cabbage is a vegetable with a large planting area among leafy vegetables. Small green (white) cabbage is relatively cold-tolerant, belongs to the straight root system, the root distribution is shallow, the leaf surface is tender, the evaporation is large, and it needs high soil moisture and air humidity. The growth period is short, and it requires loose and fertile, easy drainage and irrigation loam or sandy loam soil, and the plants are short, shallow roots, and fibrous roots are developed. Therefore, it is necessary to keep the soil moist before and after emergence, and not too much or too little water. After 3 leaves, water is indispensable, and the number of watering is increased to ensure sufficient water.
