Biological hydrogen-base soil continuous cropping yield increasing agent

Abstract

The invention belongs to the technical field of agricultural production resources and discloses a biological hydrogen-base soil continuous cropping yield increasing agent. The yield increasing agent comprises intermediate elements, microelements, sodium nitrophenolate and high-purity alpha-pimacol. The intermediate elements comprise, by mass, 39-41% of silicon, 23-28% of calcium, 18-21% of magnesium, 6-7% of iron and 5-8% of zinc. The microelements comprise, by mass, 1-2% of manganese, 2-3% of boron and 2-4% of molybdenum. Sodium nitrophenolate and alpha-pimacol account for 1.1%. The mass ratio of sodium nitrophenolate to alpha-pimacol is 2:1. The sum of mass percentages of the components is 100%. The total mass ratio of the microelements and the intermediate elements is 0.05-0.09 to 1. Through application of the soil continuous cropping yield increasing agent, the symptom of yield decreasing of crops due to continuous cropping can be obviously prevented and reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural means of production, and relates to a chemical agent for regulating soil, in particular to a biological water-based soil cropping yield-increasing agent. Background technique [0002] The "Fertile Soil Plan" formulated by the Ministry of Agriculture of my country regards the supplementation of trace elements as a national policy, which can treat medium and trace elements as the same as macronutrients, and can completely achieve the goal of high yield and efficiency increase. Agricultural experts call for returning the medium and trace elements taken from the soil by crops to the soil as soon as possible, and applying 25 kg of biohydration-based soil replanting yield-increasing agent per mu to ensure the balance of various nutrients in the soil and the needs of high yield and high quality. Medium-nitrogen, low-phosphorus, high-potassium compound fertilizers plus soil cropping and yield-increas...

Problems solved by technology

The prices of compound fertilizers and organic fertilizers are mostly relatively transparent, and severe competition has resulted in relatively low profits. Many distributors use relatively cheap magnesium sulfate to pretend to be other medium and micro fertilizers with relatively high prices. The misunderstanding of micro-fertilizers, thinking that the use of medium-micro-fertilizers has no effect, thus ignoring the use of medium-micro-fertilizers

[0006] (3) Most domestic experts learn knowledge from textbooks, and some learning materials themselves have defects, such as silicon fertilizer: it was defined as a beneficial element 5 years ago, a trace element 3 years ago, and a medium element now
