Acid soil composite modifier and preparation method thereof

Abstract

The invention relates to the field of soil conditioner preparation, in particular to an acid soil composite conditioner and a preparation method thereof. The organic fertilizer is characterized by being prepared from the following materials in parts by weight: 20-30 parts of chicken manure, 30-50 parts of chaff padding, 10-20 parts of molasses alcohol waste liquid, 5-10 parts of chitin powder, 2-4parts of humic acid, 3-6 parts of boric sludge, 10-20 parts of a compound microbial flora agent, 1-3 parts of a polymer water-retaining agent, 3-6 parts of a sargassum extracting solution, 2-4 partsof dolomite powder and 5-8 parts of wormcast. The acid soil composite modifier can adjust the pH value of soil, increase beneficial elements such as phosphorus and potassium in the soil, activate beneficial components in the soil, effectively control insect diseases and provide a good soil environment for crop growth, and has obvious effects of increasing the crop emergence rate and promoting healthy growth of plants.

Description

technical field [0001] The invention belongs to the field of acidic soil conditioners, and in particular relates to an acidic soil compound conditioner and a preparation method thereof. Background technique [0002] According to the statistics of the Food and Agriculture Organization of the United Nations, the area of ​​saline-alkali land in the world is not less than 3.95 billion hm 2 , of which 179 million hm of arable land 2 . Among them, the distribution of acidic soil in my country covers 14 provinces and autonomous regions, with a total area of ​​about 2030*104hm. Soil acidification is one of the chronic diseases that seriously restrict the development of agriculture in the world and China. Scientists from various countries have conducted long-term explorations on acidic soil improvement, and gradually formed several types of solutions such as physical improvement, water conservancy improvement, chemical improvement and biological improvement. These schemes have thei...

Problems solved by technology

In traditional production, lime is often used to improve acidic soil, but the application of lime is easy to cause damage to the root system of crops, consumes a lot of energy, is extremely wasteful of resources and cannot carry out comprehensive soil conditioning, the cost of soil improvement is high, and long-term large-scale application of lime will cause Cause soil compaction and imbalance of the three elements of calcium, potassium and magnesium; too little input of organic matter or long-term single partial application of chemical fertilizers leads to soil compaction; waste pollution leads to soil hazards such as the proliferation of harmful bacteria in the soil, heavy metal pollution, etc., resulting in crop emergence rate Greatly reduced
