Four Ways of Fertilizing New Vegetable Fields

Deeply cultivating soil and improving new vegetable land generally has poor soil quality. The tillage layer is only about 15 centimeters. When it is changed into a vegetable field, due to the increase in the number of planting ridges and nutrient consumption, the plough layer should be deepened gradually to improve its physical properties. Deep plowing time can be arranged in the summer and autumn when the vegetables are out of the garden, each deep-dip 2 times, so that the tillage layer of 25 to 40 cm.

To increase organic fertilizers to improve soil structure, there must be materials that can stabilize the structure, such as modifiers, organic fertilizers, and so on. The application of organic fertilizer can not only supply the demand of vegetables for NPK, but also promote the formation of soil aggregate structure, improve the ability to retain water and fertilizer and increase the buffer capacity of the soil. It is a material guarantee for fertilizing new vegetable fields and should be highly valued.

Planting legume green fertilization legume green manure fixed nitrogen in the atmosphere, after picking up the edible part, the returning of straw, especially the fresh stems and leaves of peas, broad bean, etc., can increase soil organic matter and nitrogen content.

Rational crop rotation of vegetables will lead to soil acidification, salinization and disease spread. In the grain reform area, special emphasis should be placed on rational rotation, making use of differences in the absorption of different types of vegetables, slowing down the excessive consumption of certain nutrients, and avoiding or alleviating the above-mentioned problems, so as to give full play to the potential of new vegetable fields. For example, arrange some mustard, peas, etc. in the rotation, can absorb phosphorus and potassium that cannot be used by ordinary vegetables, and 14% to 34% of the phosphorus and potassium are re-used in the available state to the soil to improve phosphorus and potassium nutrition for the next pod vegetable. situation. There are various rotations, but one-quarter legumes should be arranged in the rotation.
