Preparation method of crop quality and efficiency improving nutrient solution

Abstract

The invention discloses a preparation method of a crop quality and efficiency improving nutrient solution. A carbon source, a nitrogen source and yeast extract are used as main nutrient sources of bacillus subtilis and saccharomycetes strains, high-density fermentation culture is performed for 36-48 h through optimization control of process parameters such as the temperature of 25-32 DEG C, the rotating speed of 180-220 rpm, the pH of 6.0-7.0, the ventilation capacity and dissolved oxygen to obtain a fermentation culture solution, and other steps are conducted, so that the nutrient solution is prepared. Active components in a microbial fermentation culture solution are extracted, and organic and trace element components such as potassium fulvate and polyglutamic acid which are used for regulating nutrition metabolism are added in a proper proportion, so that the photosynthesis of plants is effectively enhanced, the root system is promoted to be developed, the stalks are thick and strong, and the disease resistance and lodging resistance of the plants are enhanced; and crops can be promoted to be early matured for 5-7 days, seeds are full, the rice yield is increased by 1-3%, the sugar content and VC content of vegetables and fruits are increased by 10-18% and 15-25% respectively, the quality is obviously improved, and the requirements of green and ecological agriculture development are met.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for preparing a nutrient solution for improving quality and efficiency of crops. Background technique [0002] my country has a large population and little arable land, and with the growth of population, the development of industry and cities, the arable land is decreasing year by year, so chemical fertilizers have been widely used logically. For a long time, a large number of chemical fertilizers have been used while ignoring the role of microorganisms and organic fertilizers, resulting in imbalanced crop nutrition and reduced yield and quality. In addition, extreme weather changes often trigger and aggravate crop lodging, resulting in poor crop maturity, reduced rice yield and wheat flour yield, poor taste of fruits and vegetables, reduced nutritional quality, and poor profitability. Therefore, there is an urgent need for a crop quality-enhancing and e...
