Do not go blindly when growing vegetables

In the cultivation process of melon vegetables, reasonable removal of leaves can reduce the consumption of pathogens and nutrients, but the removal of leaves must not be blind, and improper removal of leaves will affect the increase of yield.

Vegetable seedlings and colonization should be followed by increasing the number of leaves, removing the very few aging leaves. If you blindly go to the leaf at this stage, it will cause slow growth of the plant and delay the root system. However, it is imperative to cultivate, plant, and remove some of the leaves and leaves that are required for the development of a certain type of plant.

In the early period, it is necessary to reduce the number of stays. Once a lot of damage is done to the branches and leaves, in addition to hurting the roots and growing up, the fruit and leaves will also cause sunburn. Because the fruit is suddenly exposed to direct sunlight by the leaves, the sunburn spots appear on the skin; because the leaves are suddenly removed, the ratio of leaf to fruit is small, and the photosynthetic nutrient supply is insufficient, often forming a stale fruit, hollow fruit, and sharp-edged melon. In addition, excessive deleaching can cause imbalances in the plant up and down, resulting in a sudden decrease in the amount of water evaporation, often causing severe leaf curling in tomatoes and the like. Therefore, the purpose of deforestation should be clear, the quantity should be appropriate, and if it does not go, it should not go too early. Except for onions and leeks, the leaves must be cut to the leaves before they are planted, and the leaves should not be taken as necessary cultivation measures.

Sometimes, in order to re-accelerate growth, mature plants can be properly removed. For cucumber headless plants, in addition to spraying gibberellin and boron fertilizer, some large leaves can be cut to promote the germination of the new head. Because headlessness is the main contradiction at this time, the purpose of deforestation is to sacrifice and sacrifice a few leaves worth. After a bean pod has passed a batch of pods, about 1/4 of the old leaves can be removed and more new shoots can be promoted. With the new shoots, a new batch of flowers can be generated and a new batch of pods can be formed. These leaves are worthwhile too. . The hedgerow wall cucumbers need to be covered once in a while, and the lower leaves can be left under the plants and piled on the ground. However, they cannot be piled too much, and the lower leaves must be removed to prevent diseases. Peppers and bell peppers can also be removed from the main culm (ie, below the tillers) when the plants have grown. However, it is not appropriate to erase too early. Some people will wipe off all lateral buds and leaves of the main culm at a time when the diameter of the plant has not reached 20 centimeters, which is obviously unfavorable for growth and development.

There are several misunderstandings in deforestation of vegetable production:

One is that removing some of the old leaves in the lower part can save nutrition. In fact, as long as the leaves do not become yellow, the photosynthetic product it produces is much greater than the consumption. The leaves below the melon strips or fruits will play an important rooting role. The nutrient produced by the leaves of the upper part of the melons will mainly supply the growth of fruits and melons. Therefore, it is a pity that the leaves of the lower part of the melons are properly preserved, which has the effect of rooting and strong trees and preventing premature plant failure. This is a good way of prolonging the harvest period and increasing the yield.

Second, it is thought that more leaves will make the fruit of solanaceous vegetables better. I have seen that the lower fruits of some local varieties of tomatoes have just begun to color, and the leaves below the three ear fruits have gone to perfection. Some fruit in the middle of the rapid maturity, the bottom of the leaves to the light, leaving only about 3 leaves in the ear, which is obviously wrong. It is difficult to supply the nutrition of multiple fruits by three leaves, so even if the fruit is better in color, it should not be too much to leave. Too few leaves and insufficient photosynthetic products can cause problems such as slow fruit growth, increase in dead fruit, and more hollow fruit. The loss of yield is very large. This is what killed the sesame seed and lost the watermelon.

When the upper fruit of the tomato is ripe, it is only necessary to remove the individual leaves close to the fruit or remove the part that covers the fruit. It is not necessary to remove a large number of leaves for coloring. Because the main reason for the poor coloration of fruits is the temperature is too high or too low (such as daytime often higher than 35 °C or often below 15 °C), leaf shade has an effect on the color, but not the key.

The third is that the leaves can prevent pests and diseases. The main pests should be controlled by changing the environmental conditions, increasing the resistance of the varieties and spraying suitable pesticides. Although removing the leaves can remove some of the germs, eggs, and parasites that are parasitic on the leaves, it is impossible to remove them and the control effect is poor. The prevention of pests and diseases at the expense of leaf removal is not desirable. Sometimes the harmful effects of removing the leaves will be greater than those of some pests. In the case of wilting leaves caused by root diseases, sometimes removing some leaves at the beginning can make the plants temporarily no longer wilt, or make the degree of wilting lower, but the root diseases will not become lighter. This unwarranted change is temporary. It is usually thirst for drinking. It is mostly to speed up the death. It must not be possible to prevent root diseases through the leaves. The leaves are the photosynthesis plants of vegetables. Leave leaves and leaves to be rational. Take full account of the advantages and disadvantages.
