How to increase the fertility of newly reclaimed vegetable soil? Accompany fat four ways to tell you

The influence of soil fertility on the cultivation of vegetables is self-evident, but the newly reclaimed vegetable land generally can not meet the requirements of soil fertility. In order to fertilize the new vegetable fields, many people blindly apply a large amount of fertilizer, which is not conducive to the healthy growth of land fertility. Soil fertility is the basic attribute and essential characteristic of soil, the ability of soil to supply and coordinate nutrients, water, air and heat for plant growth, and the comprehensive response of soil physical, chemical and biological properties. The four major fertility factors are: nutrient factors, physical factors, chemical factors and biological factors.

There are several ways to accompany fertilizer reasonably:

1. Deep ploughing and soil improvement

The soil quality of the new vegetable land is generally poor, and the tillage layer is only about 15 cm. When it is changed into a vegetable field, due to the increase in the number of planting stubble and large nutrient consumption, the tillage layer should be gradually deepened and its physical properties should be improved. The deep ploughing time can be arranged when the vegetables come out of the garden in summer and autumn, each turning twice, so that the ploughing layer reaches 25cm to 40cm.

two。 Increase the application of organic fertilizer

In order to improve the soil structure, there must be substances that can stabilize the soil structure, such as modifiers, organic waste, organic fertilizer and so on. The application of organic fertilizer can not only supply the needs of vegetables for nitrogen, phosphorus and potassium, but also promote the formation of soil aggregate structure, improve the ability of water and fertilizer conservation and soil buffering capacity, which is the material guarantee for fertilizing new vegetable fields. We should attach great importance to it.

3. Planting legume green manure

Legume green manure fixed nitrogen in the atmosphere, after picking its edible part, the straw was returned to the field, especially the fresh stems and leaves such as pea and broad bean were pressed green, which could increase the content of soil organic matter and nitrogen.

4. Rational crop rotation

Continuous cropping of vegetables will lead to soil acidification, salinization and disease spread. In grain-to-vegetable areas, special attention should be paid to rational crop rotation, making use of the differences in fertilizer absorption of different varieties of vegetables, slowing down the excessive consumption of certain nutrients, avoiding or reducing the above problems, so as to give full play to the production potential of new vegetable fields. For example, some mustard and peas are arranged in the rotation, which can absorb and utilize the phosphorus and potassium that can not be used by ordinary vegetables, and 14% and 34% are secreted into the soil again in an available state, so as to improve the nutritional status of phosphorus and potassium for the following vegetables. There are various ways of crop rotation, but a season of legume vegetables should be arranged in the rotation.

Soil fertility is an important indicator of soil fertility, which measures the ability of soil to provide all kinds of nutrients needed for crop growth. It is the comprehensive performance of various basic properties of soil, the most essential feature that distinguishes soil from soil parent material and other natural bodies, and also the material basis of soil as natural resources and means of agricultural production. Only a reasonable method of accompanying fertilizer can make the soil fertility grow normally and healthily.
