Problems solved by technology

The increasingly serious crisis of soil resources is mainly due to the irrational use of soil resources, the abuse of pesticides and other chemical products, resulting in the degradation of soil nutrients, the continuous decline of soil organic matter content, resulting in the deterioration of soil physical and chemical properties, soil erosion, soil pollution, compaction, hardening, acidification , and the relevant agricultural by-product pesticide residues seriously exceed the standard and are discarded

Embodiment Construction

[0016] Weigh 400 kg of calcium hydroxide powder, 50 kg of potassium chloride powder, 50 kg of lime nitrogen powder, and 500 kg of pottery clay powder, mix thoroughly, spray with atomized water until wet, extrude through a granulator to form granules, and dry Packed in separate bags, such as 25kg / bag.

[0017] The present invention is put on trial in Hangzhou area, 15,000 kilograms of soil of 50cm thick soil layer per mu of acidic soil of ph6, sowing 1,000 kilograms of modified fertilizers, can make acidic soil reach neutral ph7. No organophosphorus pesticide residues have been detected in crops that have been applied with organophosphate and carbamate pesticides, and satisfactory application results have been achieved.

Abstract

The present invention discloses a modified fertility-increaisng agent for acid soil, belonging to soil containing material only containing inorganic compound. Said fertility-increasing agent is made up by using the components of calcium hydroxide, potassium chloride, cyanamid and pottery clay through the processes of mixing, spraying water, moistening, extruding, granulating and drying. Said invented fertility-increasing agent not only can be used for improving acid soil and modifying it, but also can neutralize and convert the residue of organic phosphate and carbamate pesticides in the soil into nitrogenous fertilizer and phosphate fertilizer which can be easily absorbed by crops.

Description

technical field [0001] The invention relates to a soil conditioning material containing only inorganic compounds, in particular to an acidic soil modification fertilizer. Background technique [0002] Due to the influence of the monsoon, the tropical and subtropical areas of our country have a lot of rain and high humidity, forming a unique moist red soil area, and has become one of the areas with the greatest production potential in the world. Red-yellow soil, the representative soil in the Jiangnan region, is also one of the most important soil resources in my country, widely distributed in 15 provinces, cities and regions south of the Yangtze River. Due to the use of phosphorus and potassium fertilizers, although the yield of crops was increased at that time and in the current season, their degradation products aggravated the acidification of the originally weakly acidic soil and deteriorated the soil quality. According to the survey of soil conditions in the Jiangnan ar...
