In the process of vegetable planting, dead seedlings and dead trees occur from time to time, causing unnecessary economic losses. Grasp the following four points and deal with them easily:
Fully decomposed farmyard manure
When planting, if some manure such as chicken manure and duck manure is used as the base fertilizer, it must be combined with high temperature and stuffy shed fertilization, which can be fully fermented and decomposed before applying.
If you are in the shed for a short period of time and it is too late, you can use commercial organic fertilizer that has been completely decomposed by fermentation. Once a crop of seedlings is pulled out of the garden due to burning roots, measures must be taken to promote rapid decomposing of manure in a short period of time before planting of the next crop of seedlings; moreover, ventilation should be increased before planting, so that harmful gases generated when manure decomposes are released from the shed.
Note the amount of acupoint application
Many vegetable farmers find that soil-borne diseases and insect pests occur more and more frequently when they are planting. In order to prevent soil-borne diseases and insect pests, in addition to dipping roots with chemicals, they will also use some methods of applying chemicals or bacterial fertilizers in holes to promote root prevention. Disease to protect vegetables from soil-borne pests and diseases. However, due to improper use of some fertilizers, it is difficult for the bacterial fertilizer to exert its effect or the seedlings are damaged.
This reminds the vegetable farmers, whether it is dipping the root or applying the acupuncture point, you must pay attention to the dosage. After applying the agent to the hole, the agent directly contacts the root system of the plant, which easily causes root damage, root burning or fumigation, which results in the delay of planting or dead seedlings after vegetable planting.
The activity of biological bacterial fertilizer is affected by environmental factors. If there is no effect after application of bacterial fertilizer, there are mainly these reasons: one is that the effect of biological bacterial fertilizer is slow, and it takes a certain time to slowly develop the effect; second, the lack of soil organic matter, biological Bacteria are difficult to survive, it is recommended to apply organic fertilizer or organic materials; thirdly, the application of holes is not standardized, such as filling the soil too shallow, which causes the biological bacteria to be decomposed by the sun.
Therefore, the best way is to apply biological fertilizer and organic fertilizer before planting to fully improve the soil and reduce pathogenic bacteria and insect eggs in the soil.
Choose the depth of planting
After planting, stalk rot and blight will often lead to dead seedlings. The occurrence of these two diseases has a great relationship with the deep planting. Because the planting is too deep, the stem base of the seedlings is buried in the soil. After planting, the outside temperature is very high due to too much watering, which causes the water vapor to evaporate upwards and the stem base temperature becomes very high. It will cause damage to the epidermal tissue at the base of the stem, which leads to disease infection.
Therefore, you must pay attention to the depth when planting. Too deep and too shallow will not work. The *** is ridge cultivation.
Watering should be timely and appropriate
Planting vegetables in high temperature seasons, the moisture in the soil evaporates quickly, and the transpiration of the plants will become stronger. When the seedlings are planted, vegetable farmers cannot blindly control the water. In addition to watering a sufficient amount of planting water, you should also water 1-2 times continuously, that is, slow seedling water, which is conducive to rapid slowing down of seedlings. But do not over water every time, avoid flooding.
After the planting water and slow seedling water are poured, the seedlings should be squatted and the watering time can be extended appropriately. And to promote the tree water is to water 10-15 days after the slow seedling water. Only reasonable watering can promote the root system of vegetables to deepen and form strong trees.
Water, fertilizer, soil and the depth of planting can easily deal with dead vegetable seedlings by grasping these four points.

Polysaccharide is a glycosidic bond bonded sugar chain, at least more than 10 monosaccharides composed of polymerized sugar polymer carbohydrates, can be used in the general formula (C6H10O5) n said. Polysaccharides composed of the same monosaccharides known as homopolysaccharides, such as starch, cellulose and glycogen; polysaccharides composed of different monosaccharides known as heteropolysaccharides, such as gum arabic is composed of pentose and galactose. Polysaccharide is not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducibility or change of spin. Polysaccharides are also glycosides, so they can be hydrolyzed, and in the process of hydrolysis, they tend to produce a series of intermediate products, and eventually completely hydrolyzed to obtain monosaccharides.
