It is easy to lose water in the wholesale process of fruits and vegetables. How to solve it?

Short-term water shortage will cause the stem and leaf color to fade, and the leaf edge will even turn yellow and white; Lack of water for too long will cause dry leaves, dry stems and soft vegetables. When the soil layer is dug, it will be found that the fibrous roots of plants are stripped of soil and dehydrated. Fibrous roots even have the phenomenon of "hair loss". Growing vegetables in our family is a traditional model, which is generally based on the growth and leaf surface of vegetables. If it doesn't rain for a long time and the land doesn't keep the tide, then when the vegetable leaves wither or grow slowly, we will think it is water shortage.

You can check whether there are water drops on the top of the leaves of vegetables on a sunny morning, preferably before the sun comes out. If the surface is not short of water at all, a layer of water vapor and a drop of water represent different States, which can be carefully observed. Irrigation from June to September should be determined according to rainfall. If there is a lot of rain and the air humidity is high, irrigation should be less. If there is little rain and the weather is dry, the frequency and quantity of irrigation should be increased appropriately. Starting from mid-September, the amount of irrigation should be gradually reduced according to crop growth and weather conditions.

Generally, soil with a depth of 10cm is taken. If you grab it with your hands and put it down waist-high, it means that the soil moisture is suitable and there is no need to water it. The soil can't catch the ball, indicating that the soil is short of water and needs watering; Catching water and sticking to the ground means that there is too much water in the soil and there is no need to water it. Observe the growth of tender leaves at the top of vegetables. Because the tender leaves at the top of vegetables that are not short of water are generally vigorous, not weak and not drooping. If it is a water-deficient vegetable, the tender leaves at the top will obviously soften, and the leaves that are not lush and serious will droop.

The weather is very hot, and the continuous high temperature needs proper watering. At this time, vegetables will be seriously short of water, affecting growth. ? Base fertilizer is mainly applied before vegetable planting. Generally, fully decomposed farmyard manure is the main fertilizer, and then auxiliary fertilizers such as phosphorus, potassium and calcium are added appropriately. Because farmyard manure has a lasting effect and can provide nutrients for the growth and development of vegetables for a long time, it must be fully applied before planting.
