Description
Technical Field
The invention relates to a planting method for soil improvement.
Background
The traditional fertilization concept considers that the fertilizer is 'nitrogen-free and not large, phosphorus-free and not red, potassium-free and not sweet', namely nitrogen, phosphorus and potassium must be applied in the plant growth process, otherwise, the quality of crops is affected, and even the yield is reduced, therefore, in order to pursue the quality and the yield of the crops, people apply a large amount of fertilizers of nitrogen, phosphorus and potassium, but no obvious yield increase is seen, even the quality of the crops is reduced, the problem that the land is fed more and more 'thin' is also caused, once the usage amount of the nitrogen, phosphorus and potassium is reduced, the quality of the crops is immediately reduced and the yield is reduced, in order to solve the problem of reducing the usage amount of the fertilizers of the nitrogen, phosphorus and potassium, but the problem of not reducing the yield is solved, the utilization rate of the fertilizers is improved as the main research direction at present, and the fertilizer is divided into two types: one is adding synergist to improve utilization rate of NPK, such as adding digestion inhibitor, urease inhibitor, alginic acid and fish protein; the other is to coat the fertilizer, and the purpose of fertilizer synergism is achieved through slow release.
The nitrogen, phosphorus and potassium fertilizer is applied for a long time, so that soil hardening and salinization are serious, particularly, in a vegetable greenhouse, farmers apply a large amount of fertilizer to obtain higher yield, so that a large amount of fertilizer is not absorbed by vegetables and remains in the soil, the greenhouse is a relatively closed environment, the temperature and humidity in the greenhouse are relatively high, the soil transpiration is also high, and salt remaining in the soil moves up and accumulates along with water to cause salt accumulation on the surface layer of the soil. Soil in the closed greenhouse cannot be washed by rainwater, and the artificial irrigation only relates to the surface layer, so that salt on the surface layer cannot be washed away. Improper fertilization leads to severe soil hardening, which is the reason for "more and less soil being fed".
In the face of the problem of 'more feeding and thinner soil', people begin to want to solve the problem, an organic and inorganic combined fertilization mode appears, 2004 years of organic and inorganic fertilizers have come to life, people want to improve the soil by adding organic matters, however, over the years, the soil problem still cannot be solved, particularly vegetable greenhouses and even increasingly severe forms appear, many greenhouses are whitened, greenish and even reddish in soil, the planting is not suitable, even if the planting is reluctant, the yield is low, the fruit quality is poor, and therefore, sheds are laid down in some places, and people want to restore the soil by sheds.
At present, no better method for improving soil exists.
Disclosure of Invention
The invention provides a planting method for soil improvement, which solves the technical problems that 1) the quality of crops is reduced and the yield is reduced because the crops are planted without using phosphorus-potassium fertilizer; 2) improving the soil.
In order to solve the technical problems, the invention adopts the following technical scheme:
a planting method for improving soil, which comprises the following steps,
planting in soil with excessive nutrients in a manner of phosphorus and potassium free;
improving the soil by using a soil conditioner;
the soil with surplus nutrients has effective phosphorus content of more than 100mg/kg and quick-acting potassium content of more than 150 mg/kg;
the soil conditioner does not contain artificially added phosphorus compounds and potassium compounds, and contains calcium compounds and magnesium compounds.
Preferably, the calcium compound and the magnesium compound are both water-soluble and do not undergo a precipitation reaction therebetween.
Preferably, the application amount of the soil conditioner per mu is 1-30 kg.
Preferably, the soil conditioner also contains vitamin D3.
The artificially added phosphorus compound is one or more of monopotassium phosphate, monoammonium phosphate, diammonium phosphate, calcium magnesium phosphate fertilizer and compound fertilizer containing the raw materials; the artificially added potassium compound is one or more of potassium sulfate, potassium nitrate, monopotassium phosphate, potassium chloride and compound fertilizer containing the raw materials; the calcium compound is one or more of ammonium calcium nitrate, calcium chloride and disodium calcium ethylene diamine tetraacetate; the magnesium compound is one or more of magnesium sulfate, magnesium nitrate, magnesium chloride and disodium magnesium ethylene diamine tetraacetate.
The invention has the following beneficial technical effects:
1. by matching calcium and magnesium in the soil conditioner, the planting method does not affect the crop yield and can even improve the crop quality.
2. The planting method without phosphorus and potassium can improve soil and effectively relieve the problems of soil salinization and hardening.
3. The application can further promote the crop quality through the mutual matching of calcium and magnesium and vitamin D3 in the soil conditioner, and the yield is also slightly promoted, so that the effect is better.
