How to fertilize new garden soil?
In the adjustment of agricultural structure, some of the original plots for growing food crops have now been changed to vegetable gardens. Some farmers report that these sites are difficult to obtain high yields for a while, and asked what measures to fertilize the soil as soon as possible. The author believes that the focus should be on the following point: Dry ploughing and ploughing and ploughing and soil preparation are important measures for fertilizing vegetable soils, especially when paddy fields are replanted with vegetables, because the plough layer is shallow, which is not conducive to the growth of vegetables. Therefore, it is necessary to start planting and turn over the sun in the order that the amount of fertilizer to be grown is small and the amount of fertilizer to be used in the latter type is large. Deepen the topsoil layer year by year to speed up soil maturation, loosen the soil, improve permeability, and increase soil fertility. Dry ploughing and drying is 15-20 days earlier than vegetable growing to improve environmental conditions. Otherwise, premature aging or cyanosis may occur, which reduces stress resistance. Generally, the depth of ploughing should be about 15-20 cm. When plowing the soil, it is necessary to do a good job in the drainage of the soil in the paddy field and establish the drainage and irrigation system for the vegetable garden. Each vegetable plot needs to be equipped with a three-groove system so that the rain will stay dry and the cool soil will promote growth. For the arrangement of rice fields for vegetable plots as the next season or the following year, it should be possible to turn the sun on after harvesting the previous season crops. Especially in winter and summer, freeze hoeing is used to achieve soil loosening, killing germs and reducing the number of insects. In order to facilitate the formation of deep plowing layer and soil aggregate structure. Increase the application of organic fertilizer in the plough before the full maturity of the farmyard fertilizer, not less than 5000 kg per acre, and then dig deeper to reach the flatland soil, soil and fertilizer. After planting vegetables, human feces or high-quality farmhouse manure roots can be applied, which can significantly increase soil organic matter content, increase soil aggregate structure and fertility. Conditions can be used Chen wall soil, weathered ponds, ditch, river mud, etc., mixed with soil, will help improve the soil structure. Rice paddy soil is generally more viscous, can be mixed with sand in the late growth of vegetables, can also be foliar fertilizer, to supplement nutritional needs, fresh garden soil is easy to compact, before and after fertilization is best to perform a shallow cultivator, loose soil, conducive to Absorption of nutrients. Rational rotation of rice fields into vegetables is an effective form of crop rotation, the principle is the first kind of vegetables that require fertilizer, and first legume bean or Chinese cabbage, rape and so on. The vegetable growth cycle is shorter and the crop rotation is more frequent, and the root activity has a greater impact on the soil. Therefore, rational rotation is particularly important. For example, leguminous and non-fabric, deep-rooted and shallow roots, dense planting and sparse planting, hi-nitrogen and phosphorus-potassium vegetable rotations are conducive to soil nutrient regulation, rational use of fertility, and reduction of pests and diseases. . Various localities can use different rotation methods according to their own specific conditions to provide a good soil environment for the growth of vegetables.

Combine straw returning with ploughing and soil preparation, and apply 250-500 kg of crop straw or green manure to each acre of vegetable land, and increase the content of organic matter year after year by ploughing into the soil. During the growing period of vegetables, various finely divided crop stalks or green manures may be properly covered in the rows or on the surface of the car, and they may be ploughed into the soil by cultivating the loose soil, or the finely divided straw may be put into the car ditch. Thickness of 3-5 cm is appropriate. If the amount is too large, when the straw rots, it will burn and damage the root system of vegetables, which will affect the growth.
