In the past maintenance of vegetable production, the vegetable farmer's habits put the attention on the conditions of improving the space of temperature, light, gas, etc., and the work of improving the soil environment, inventing a work that is conducive to the development of the root system and persisting in its vigorous vitality, does not pay attention to . "The roots are deep and only Ye Mao", only the root group that has developed and has strong vitality, can achieve high yield and high quality. The main agricultural measures that promote the development of root systems are:
1. Deeply increase the application of farmyard manure
Deep turning is to eliminate the soil compaction and add the root of the living soil layer. In the deep turn together, a large amount of farmyard manure is applied, and a new high-fat film is sprayed together. Not only can the nutrients of the long-acting multi-element of the crop be supplied, but also the soil structure can be improved, the physical and chemical functions of the soil can be improved, and the growth of the vegetables can be provided. Excellent soil conditions for conditions of permeability and buffering.
2. Cultivate multiple seedlings and protect the roots
The fundamental roots of most vegetables are formed during the nursery period. During the nursery period, the seedlings with developed roots are cultivated, and these root groups are maintained during the seedling process and during transplanting and planting, which not only facilitates the growth of the seedlings, but also has an important effect on future growth and development. From the point of view of mulberry roots, it is necessary to raise seedlings in containers such as nutrient bowls, plastic drums or paper bags. During the nursery period, the seedlings of the seedlings can be used to induce the onset and deep stalk of the new roots.
3, formula science fertilizer
Different fertilizers have different effects on the development of roots. For example, calcium directly affects the growth of apical meristems. Zinc determines the growth rate of root tips. Phosphorus can promote the division, proliferation and extension of root cells. Understand this truth, regardless of the fertilizer on the seedbed, it is still necessary to pay attention to the application of superphosphate and zinc sulfate. If a certain amount of edible vinegar is incorporated into the calcium phosphate fertilizer, it can constitute calcium acetate with a certain solubility, which enhances the absorption of calcium by the crop.
4, pay attention to maintaining the root system
Roots are damaged during their life by low temperatures, high temperatures, salt buildup, fat burning, and mechanical damage. At low ground temperatures, the roots will have cold roots and roots, and high temperatures will cause the roots to age too quickly. The high solution concentration of the soil will damage and inhibit the root tip and root hair, and the absorption capacity of the root system will be greatly reduced. The improperly applied or unsuitable cultivating loose soil may directly damage the root system.
Therefore, in the greenhouse vegetable production, in the deep-turning soil to increase the application of organic fertilizer on the base, when cultivation, suitable planting (cultivation), practical cover and removal of plastic film, scientific fertilizer and ploughing soil, etc. It is a necessary way to maintain the root system.
5, take the opportunity to promote the rehabilitation of the root system
In the long-term cultivation of greenhouse vegetables, after a certain period of time or after suffering from adverse conditions such as low temperature, in order to promote the recovery of roots quickly, it is generally necessary to use the medicine or calcium, phosphorus and zinc compound fertilizer.
