Generally speaking, planting agricultural greenhouses can quickly recover costs and create more benefits. Various crops need to be planted continuously. In this way, the land in the greenhouse will not get any leisure, which will lead to a serious decline in soil fertility. Agricultural greenhouses are completely dependent on the use of inorganic materials. Nutrition is supplemented by applying chemical fertilizers, but chemical fertilizers cannot fundamentally solve the problem. It will also harden the soil, antagonize ions, and produce vegetables and other crops that do not meet the prescribed standards. Therefore, increasing fertility, promoting nutrient balance. And increasing the production potential of greenhouse soil are basic measures for high yield and quality of crops. The soil fertility sensor can effectively detect soil fertility and improve the soil in time.
How to fertilize
Fertilization: The newly-built greenhouse soil generally has low organic matter and low nitrogen, phosphorus, potassium and other nutrients. Use the portable soil nitrogen, phosphorus and potassium rapid measuring instrument to insert the soil to detect the soil nitrogen, phosphorus and potassium content. In order to see if it is necessary to increase the amount of fertilizer to improve soil fertility. You can apply a large amount of manure and other organic fertilizers, but they must be fully decomposed and spread evenly before plowing.
How to improve the soil of agricultural greenhouses
Soil improvement: when building a new greenhouse with machinery such as bulldozers. The original farming layer of the soil. This is what we call “mature soil”, which is basically pushed into the back wall. The soil in the greenhouse is the original farming layer and the soil underneath is the “raw soil”. How to improve the soil is the key to high yield of melons and vegetables. The soil fertility sensor can check different soil conditions according to soil texture. If conditions permit. It can properly improve the soil composition, insert clay, and mix sand appropriately. Sand should be mixed with clay to improve soil quality.
Deep overturning: During the construction of the greenhouse, the mechanical and manual rolling of bulldozers and other machinery will make the soil hard and compact. The original structure of the soil was severely damaged. By deep plowing the soil and adding organic fertilizers, the soil can be loosened and improved, which is conducive to the growth of the roots of melons and vegetables. After applying fertilizer, when turning the soil. Do not use rotary tillers, plows and other agricultural tools, especially rotary tillers, because the depth of the cultivated land is not enough. Use a shovel to rotate the depth of the two shovel by hand to make the rotation depth reach 40-50cm, and turn the applied fertilizer evenly.
