Description

Growth regulator for retention-type carbonaceous mud field and application thereof Technical Field The invention relates to the technical field of plant growth regulators, in particular to a growth regulator for a retention type carbonaceous mud field and application thereof. Background The retention-type carbonaceous mud field refers to retention-type rice soil formed by soil developed by carbon shale weathered matters, and is mainly distributed in four areas of Ganza, shangrou Fuzhou and Jian in Jiangxi. The mother substance of the retention type carbonaceous mud field contains more organic carbon components, the color of each layer of the section is darker, the black is gray, the texture is generally slightly sticky, and the mother substance of the retention type carbonaceous mud field contains a small amount of gravel. The soil organic matter content of the retention type carbonaceous mud field is 6.1 percent+/-0.7 percent, and the carbon-nitrogen ratio (C/N) of the soil is 15-30. The carbon sludge Tian Gao C/N ratio of the retention type has the influence on the soil nitrogen supply dynamic and the soil physicochemical environment, and the influence on insufficient or delayed nitrogen supply in the key growth period (especially in the young ear differentiation and the grouting period) of the rice, so that the nutrition quality and the rice milling quality of the rice are reduced. At present, a large number of methods and products for improving the yield and the quality of rice are available on the market, but the method mainly aims at improving the organic matters and the nutrient content of soil, and the research on the influence of high C/N ratio of the retention type carbon muddy field soil on the quality of rice is little.
