Embodiment Construction

[0019] Such as figure 1 Shown:

[0020] The main method and step of implementation: 1, select earthworm: select the earthworm (Daping No. 1) through cow dung feeding for use, this kind earthworm has strong reproductive ability, many wrinkled body surfaces, is rich in polypeptide high nutrition, and nutrient is easy to hydrolyze; 2. Collect earthworms: separate earthworms and earthworm dung manually, and then wash earthworms with clean water (tap water) to remove dung on the surface of earthworms; 3. Treatment of earthworms: put clean earthworms and clean water at 25°C in a ratio of 1:10 Soak for 72 hours at a constant temperature, then stir for 2 minutes, centrifuge for 10 minutes, and settle for 30 minutes; 4. Obtain the original solution of earthworms: use medical gauze to filter the precipitated solution, add an appropriate amount of deodorant to the filtered solution and stir evenly as the original solution; 5. Spray Preparation of application solution: Prepare the origin...

Abstract

The invention relates to a method for improving the yield of super-sweet corn. The method comprises the steps of selecting earthworm: selecting the earthworm fed with cow dung; collecting the earthworm: artificially preliminarily separating the earthworm from wormcast, and cleaning the earthworm with clean water to remove the wormcast and earth from the surface of the earthworm; treating the earthworm: mixing the earthworm with clean water, soaking at a constant temperature, stirring, centrifuging and precipitating; acquiring an earthworm stock liquid: filtering the precipitation solution by using medical gauze to obtain filtrate; preparing spray liquid: preparing the earthworm extract stock solution into the spray liquid with concentration of 30%; and spraying the spray liquid onto the super-sweet corn. The method overcomes the defects of complex programs, fussiness in application, high cost, no adverse effect and the like in the prior art. By adopting the method, the cluster yield of the super-sweet corn is improved, the commodity performance and the nutrient value of super-sweet corn grains are improved, the harvest time of clusters is prolonged, the weight gain of individual fruit is obvious, organic, harmless and ecological production of the super-sweet corn can be realized, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to biological fertilizers, which use natural biological fertilizers to promote the production increase of super-sweet corn, in particular to a method for increasing the production of super-sweet corn. Background technique [0002] Before the present invention was made, the existing methods for increasing the production of super sweet corn were mainly realized by increasing the use of chemical fertilizers or using a large amount of organic fertilizers, which had complex operating procedures, cumbersome operations, high unit cost of use, and were unfavorable to the realization of ecological and environmental protection goals. At present, there are few studies on increasing the yield of super-sweet corn by topdressing natural bio-fertilizers outside the roots, especially the use of earthworm compound solution to improve the yield and flavor of super-sweet corn. One of the technical problems of super sweet corn planting is the short h...
