Method for improving dry farmland soil

Abstract

The invention relates to the technical field of soil conditioner preparation, in particular to a method for improving dry farmland soil. The method comprises the steps that before dry farmland farming, 45 kg of fertilizer maintenance conditioners are evenly scattered to every mu of dry farmland; deep ploughing and soil turning are carried out, and the depth is not smaller than 30 cm; fertilizer adding conditioners are evenly scattered to the ploughed farmland, and are formed by blending, by weight ratio, the following raw materials of 40 parts of nitrogenous fertilizer, 15 parts of phosphatic fertilizer, 12 parts of potash fertilizer, eight parts of nitrogen-fixing bacteria powder, six parts of fulvic acid, four parts of aminosalicylic acid, 55 parts of biogas rotten straw manure and 35 parts of grain residue manure; the soil is leveled through a rotary cultivator, and the aim of improving the soil can be achieved. Fertilizer maintenance improvement is firstly carried out on dead soil, and the soil is made to have good fertilizer maintenance capacity. Then, fertilizer adding improvement is carried out on the soil, the soil is made to have nutritious base fertilizer, and the effect of reducing the usage amount of fertilizer is obvious. Under the action of silicon dioxide micro powder, the soil is made to have the good fertilizer maintenance effect, and nutrient elements in the soil are prevented from being lost.

Description

technical field [0001] The invention relates to the technical field of soil improver preparation, in particular to a method for improving upland soil. Background technique [0002] Cultivated land is the basic resource and condition for human survival. Entering the 21st century, the population is increasing, the cultivated land is gradually decreasing, and people's living standards are constantly improving. To maintain sustainable agricultural development, we must first ensure the quantity and quality of cultivated land. According to incomplete statistics from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Food and Agriculture Organization (FAO), the land area of ​​the world is about 1.829 billion hectares, and the per capita arable land is 0.26 hectares. As of December 31, 2011, the amount of cultivated land in the country was 1.82476 billion mu. Basic farmland refers to the cultivated land that cannot be occupied for a long time det...

Problems solved by technology

Because basic farmland is the essence of cultivated land, strengthening the protection of basic farmland and implementing special protection for high-quality cultivated land has played a positive role in ensuring national food security. , are diverse, so the damage to the current soil is relatively large, and there are still a large amount of chemical substances in the soil. This kind of soil has a great impact on the actual planting of crops, which will cause slow growth of crops and poor disease resistance.

[0003] At present, a major problem still exists in most of the cultivated land in my country is that the soil fertilizer retention capacity is poor, and the nutrients required for crop growth are lost quickly, and a large amount of topdressing chemical fertilizers are needed to meet the nutrients required for crop growth.
