Description

Special water-soluble soil conditioning package for saline-alkali soil and preparation method thereof

1. Technical field

The invention relates to a preparation and use method of a soil conditioning package, in particular to a preparation and use method of a water-soluble soil conditioning package special for saline-alkali soil, belonging to the technical field of fertilizer production.

2. Background art

Soil is the root of agricultural planting, and a healthy soil environment is an important guarantee for agricultural development. In recent years, the acid-alkalization salinization of soil is increased due to unreasonable cultivation, excessive planting, unscientific fertilizer use and the like widely existing in various main agricultural areas in China. Saline soil and alkaline earth often coexist in a mixed manner, collectively referred to as saline-alkaline earth. The saline-alkali soil has high salt content, low organic mass, high pH value, poor ventilation and water permeability, and is lack of large, medium and trace elements such as nitrogen, phosphorus, potassium, iron, calcium, boron and the like. Saline-alkali becomes one of the important factors affecting the yield of crops at present, and restricts the healthy growth of crops, so that the yield of crops is reduced to a great extent, and the data show that the saline-alkali hazard causes about 40% yield loss.

At present, the area of Chinese saline-alkali soil is about 2000 ten thousand hectares, and so far about 80% of the Chinese saline-alkali soil is not developed and utilized. The improvement and utilization of saline-alkali soil is a forced matter at present of increasingly lacking cultivated land resources and serious ecological environment damage.

CN 105567240A discloses a method for preparing soil conditioner by using fowl feather, which is prepared by a series of reactions between amino acid obtained by hydrolyzing fowl feather and citric acid, and medium trace elements. The liquid soil conditioner has the defect that on the basis of improving soil, only medium trace elements with fixed content and proportion can be provided for crops, but large amount of major elements with large growth demand are not provided for crops. CN104261988B discloses a special suspension liquid compound fertilizer for saline-alkali soil and a preparation method thereof, wherein the compound fertilizer comprises nitrogen fertilizer, boron fertilizer, EDTA-Zn, EDTA-Mn, humic acid powder, calcium fertilizer, phosphate fertilizer, potash fertilizer, organic matters, soil conditioner, microbial inoculum, wetting dispersant, emulsifier, thickener, antifreezing agent and water in parts by weight. The fertilizer has the defects that the fertilizer mainly provides various nutrient elements required by crops, the soil conditioner is only one of the components of the compound fertilizer, and the conditioner is one or more of mineral powder, is a water-insoluble substance and cannot quickly and effectively improve the acidity and alkalinity of soil. CN 101323548B discloses a plant acid-alkali fertilizer for treating saline-alkali soil, which is prepared from plant straw 37-60%, plant acid 21-42%, compound amino acid 10-26%, polyamide 1-4% and acid liquor 1-4% with total amount of 100%, and has the disadvantages of providing soil improving substances only and not providing large, medium and trace elements necessary for crop growth.

In summary, although there are various special products for improving saline-alkali soil in the market at present, the special products exist in a single product, and the direct improvement of soil and the provision of nutrition for improving stress resistance of plants are not scientifically and reasonably matched in a package manner; the nutrient elements which are beneficial to enhancing the stress resistance of crops can not be matched with the soil conditioning in different growth stages of the crops, so that the purposes of improving the soil, enhancing the stress resistance of the crops and increasing the yield and income are achieved; the special fertilizer or soil conditioner for the saline-alkali soil is difficult to comprehensively apply in a precise water and fertilizer integrated system, because low-grade fertilizer and impurities are difficult to pass through the water and fertilizer integrated filtering system.

In order to overcome the defects of the prior art, the invention provides a water-soluble fertilizer package which can be used for preventing and improving soil salinization of a water-fertilizer integrated system so as to solve the problem of preventing and controlling soil salinization under the condition of water-fertilizer integration. The soil conditioner can effectively improve the physical and chemical properties of soil, simultaneously meet the requirements of crop growth on various nutrient elements, can condition the soil in stages and with emphasis, and is matched with the nutrient elements which are favorable for enhancing the stress resistance of plants, and the soil conditioner induces the plants to improve the autoimmune power, so that the re-accumulation of salt is avoided, and the occurrence of the symptom of lack of nutrients of crops can be effectively prevented.

Under the T2 treatment, on the basis of the habit of peasants for fertilization, a soil conditioning package is used. Before sowing, the component A: the special soil conditioner is diluted by water for 150 times and uniformly sprayed on the ground surface, urea and diammonium are applied on the ground surface, and then ploughing is carried out. Component A in reproductive phase: diluting the special soil conditioner by 300 times, performing drip irrigation or flushing, and mixing the component B: the special nutrient is diluted 1500 times for foliar spraying once, and the time interval is 12 days.

TABLE 6 impact of saline-alkali soil conditioning packages on cotton yield and soil

As can be seen from Table 6, on the basis of conventional fertilization, the cotton yield (T2 treatment, 149 kg/mu) under the soil conditioning package described in example III was increased by 44 kg/mu compared with that of peasant conventional fertilization (T1 treatment, 105 kg/mu), and the postprandial yield was increased by 42% compared with that of conventional fertilization by using the soil conditioning package. And the application of the special modifier package for the saline-alkali soil can reduce the total salt content and the soil density of the soil, reduce the pH value of the soil and improve the content levels of quick-acting nitrogen, phosphorus, potassium and organic matters in the soil to different degrees.
