First, prevent
Although the growth of various crops is inseparable from fertilizers, especially the vegetables with long growth cycle have greater requirements on soil fertility. In the eyes of vegetable growers, the growth of vegetables is good and bad, and the yield is directly related to the amount of fertilizer applied. Relationship, but if fertilization is improper or too much fertilization will have a negative impact on vegetable production. Several common fertilizers in production are:
1. Dehydration-type fertilizers Due to excessive application of chemical fertilizers at one time, or excessive application concentration, or insufficient soil moisture, after fertilization, the concentration of fertilizer in the soil is large, causing reverse osmosis of water in vegetable cells, causing dehydration of vegetables, often causing wilting of vegetables. Like frost or boiled water, light people affect the normal growth and development of vegetables, and severe cases cause death.
2, burn-type fertilizer Some fertilizers, such as ammonium bicarbonate in the case of high temperature, it is easy to produce a large amount of ammonia gas, burn vegetable leaves, lighter vegetables lower leaves tip yellow, heavy all red yellow dead. In some sheds, the application of unbleached chicken manure causes root burning and burning.
3, poisonous fertilizer Some fertilizers such as lime nitrogen, if improperly applied (direct application), will be transformed in the soil, a toxic substance is produced during the decomposition process, poisoning the roots of vegetables.
Second, balance
In order to make vegetables and their roots free from fertilizers, and to maximize the soil fertility and promote the growth of vegetables, it is necessary to balance fertilization.
Balanced fertilization refers to all the plants of crops, which can reasonably absorb the various nutrients needed for their robust growth in a certain proportion and quantity. At the same time, it means that the nutrients obtained from the soil by the crops are balanced by the fertilization, air and water, and the nutrients returned to the soil are balanced, the crops are high-yield, and the soil is not compacted.
In the middle of vegetable growth, the selection of a suitable special compound fertilizer is the key to balanced fertilization. The purpose of production and use of compound fertilizer is to meet the requirements of agricultural science fertilization and economic fertilization, and to achieve balanced fertilization. Due to the use of compound fertilizer, the cost of storage, transportation and application can be saved, and the fertilizer can be rationally formulated to ensure the yield increase effect, especially for the local soil nutrients and special compound fertilizers produced by crop varieties. The effect is better, so choose a suitable special one. Compound fertilizer is the key to balanced fertilization and an important measure to develop high-yield, high-quality and high-efficiency agriculture.
In order to balance fertilization in current production, a formula fertilization method can be adopted. Formulated fertilization is to make an accurate test in the case of a comprehensive understanding of the shed age, the types of vegetables grown in the shed and the growth of the shed, and then give a scientific and reasonable formula in combination with the varieties of vegetables to be planted in the squat. In this way, the nutrients needed for the growth of vegetables can be fully and fully supplied, and at the same time, some diseases can be avoided to some extent.
