Appropriate amount of fertilizer and fertilizer in summer

Fertilizer when appropriate, excessive prone to cause damage. If the fertilization concentration is too large, especially when the weather is hot and dry, the concentration of the soil solution is likely to be greater than the concentration of the root cell fluid, causing the cells to lose water and causing the plasmolysis to separate, causing the stems and leaves to wither. At the seedling stage of crops, if fertilizer is applied excessively, it will be more prone to produce fertilizer. Therefore, fertilization should pay attention to see the sky, see seedlings, see fertilizer, should be light should not be concentrated, appropriate amount of timely application to prevent the occurrence of fertilizer.

The type of fertilizer damage is water type. Due to too much fertilizer or insufficient soil moisture, the concentration of fertilizer in the soil is large, causing the reverse osmosis of the water within the crop cells, resulting in dehydration of the crops, which often causes the crops to appear wilting, like frostbite or hot water, and light affect the normal growth of crops. Development, severe death.

Burn-type fertilizer. Some chemical fertilizers, such as ammonium bicarbonate applied at high temperatures, are prone to produce large amounts of ammonia, burn the leaves of the crops, and the lower tips of the light crops are yellow, while the heavy ones are all red and yellow.

Poisonous fertilizers. Some fertilizers, such as lime nitrogen, will be decomposed in the soil to produce a toxic substance that will poison the roots of the crop. After the application of excess ammonium sulfate, the roots of the crop will become black due to the poisoning of hydrogen sulfide, causing crop growth to be hindered or even to death.

Other fertilizer harm phenomenon. Urea is a high-concentration fertilizer and contains biuret. Using urea as a seed fertilizer or seed dressing will affect its germination and even lose its germination power. Excessive superphosphate seed dressing can also affect seed germination. Soak soybean seeds with 1% boron fertilizer for 4 hours and sow without sprouting. Excessive chlorine fertilizer can seriously damage chlorine-sensitive crops.

The scientific application of fertilizer and fertilizer to prevent fertilizer damage should be applied scientifically. It is best to apply it deeply, and it is about 10cm away from the root; urea should not be used as a seed fertilizer; the amount of superphosphate seed dressing should not be too much; Is watered or mixed with soil application; ammonium bicarbonate should not be applied at high temperatures; lime nitrogen can be used as a base fertilizer, can not be top dressing, seed fertilizer application, but also mixed with fine soil or farmyard fertilizer, after the accumulation of arsenic to eliminate toxin after application; increase Apply organic fertilizer, organic fertilizer must be cooked before application.
