Embodiment Construction

[0016] Steps of the present invention:

[0017] Earthworms, cleaning, soaking, filtering, deodorization; earthworms from stock solution to spray.

[0018] The specific description is as follows.

[0019] First collect earthworms that feed on cow dung, wash the excrement on the surface of the earthworms with clean water (tap water), then mix according to the ratio of earthworms: water = 1:9, soak at room temperature (about 25°C) for 72 hours, and fully stir and settle. Filter with medical gauze, then add an appropriate amount of deodorant to the filtrate and stir evenly for later use. The points to note are: (1) The earthworms should be cleaned thoroughly; (2) The best soaking temperature is about 25°C, which is conducive to the function of earthworm hydrolase; (3) The soaking time must be guaranteed, too short to make the amino acids in the body cavity of earthworms effective Hydrolysis, if the time is too long, the small peptides of the hydrolyzed products of earthworms wil...

Abstract

The invention relates to a method of using earthworm composite liquid for increasing the wheat yield. According to the method, earthworms feeding on cow dung are collected and cleaned with clear water, the earthworm composite liquid is formed by mixing the earthworms and clear water of which the ratio is 1:9, soaking is carried out at normal temperature, and the earthworm composite liquid is sprayed at the later full-bloom stage of wheat. The method overcomes the defects that a large amount of existing bio-organic fertilizer is used, the existing bio-organic fertilizer takes effect slowly and is high in cost, considerably different effects are produced when the existing bio-organic fertilizer is applied at different stages, and therefore the effect of the earthworm composite liquid is limited. According to the method, the natural bio-organic fertilizer which is the earthworm composite liquid is used for replacing the traditional bio-organic fertilizer, so that the defects that a large amount of traditional bio-organic fertilizer is used and takes effect slowly are overcome; the earthworm composite liquid is spayed on leaves at the later full-bloom stage of the wheat, so that the purposes that the earthworm composite liquid takes effect rapidly, use simpleness and convenience are achieved, and topdressing is conducted during production of the wheat in a harmless and ecological mode are achieved, and the wheat yield and comprehensive benefits are improved obviously.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for increasing wheat yield by using earthworm compound solution. Background technique [0002] Before the present invention, existing earthworm compound solution is used for the technology of wheat production aspect mainly to improve wheat photosynthetic capacity, nitrogen absorption capacity, seed germination catalase activity, seed vigor index, three-leaf stage dry weight etc. by soaking seed mode. Increase the economic yield of wheat. General bio-organic fertilizers have the defects of large dosage, slow effect, and high cost. In addition, the effects of different application periods vary greatly, which limits the effect of earthworm compound solution. Contents of the invention [0003] The purpose of the present invention is just to overcome above-mentioned defect, develops a kind of method that utilizes earthworm compound solution to realize whea...
