Description
Technical Field
The invention relates to the technical field of stem borer control, in particular to a method for controlling sugarcane stem borers by silkworm excrement.
Background
At present, chemical pesticides are generally adopted in methods for preventing and treating sugarcane borers. The prevention and control mode can kill natural enemies of the sugarcane borers, pollute the environment, cause ecological damage and be not beneficial to ecological sustainable development; the sugarcane product also has pesticide residue which is harmful to human health; and the investment labor is large, the cost is high, and the effect of preventing and treating the borer is not high.
In the existing research, the prevention and control of borers increasingly focuses on pollution-free and pesticide residue-free prevention and control, for example, a method for preventing and controlling borer pests disclosed in patent No. CN201810114554.2 releases a mixture of trichogramma eggs and beauveria bassiana spore powder to a target prevention and control area to prevent and control target borers; the method can effectively control pests. The faeces Bombycis is faeces of larva of silkworm of Bombycidae. The faeces Bombycis contains N, P, K and trace elements such as copper, iron, and zinc, and is rich in chlorophyll, pectin, alkaloid (DNJ), phenols, flavonoids, and polypeptide protein. The alkaloid DNJ has strong alpha-glucosidase inhibitory activity, and has an inhibitory effect on the development of sugarcane pests. But the application of the silkworm excrement to the control of the sugarcane borers is not found at present.
Disclosure of Invention
The invention overcomes the defects that the chemical pesticide adopted in the prior art is used for preventing and treating the sugarcane borers, pollutes the environment, causes ecological damage and is not beneficial to ecological sustainable development; the sugarcane product also has pesticide residue which is harmful to human health; and the technical problems of more labor input, high cost, low effect of preventing and treating the stem borers and the like are solved, and the method for preventing and treating the sugarcane stem borers by the silkworm excrement is efficient, green and environment-friendly, reduces the input cost and can improve the yield and the quality of the sugarcane.
In order to solve the problems, the invention adopts the following technical scheme:
a method for preventing sugarcane borers by silkworm excrement comprises the following steps:
(1) and (3) disinfection and sterilization: before silkworm breeding, spraying chlorine-containing bleaching powder solution on the ground of a silkworm room for disinfection, and in the silkworm breeding process, spraying fresh lime powder on the surface of a silkworm seat to kill pathogenic bacteria;
(2) collecting silkworm excrement: collecting silkworm excrement after all cocooning; the silkworm excrement collecting method comprises the following steps: adding beneficial microbial agent onto faeces Bombycis before removing faeces Bombycis from silkworm room, and removing faeces Bombycis;
(3) composting and fermenting: conveying the silkworm excrement treated in the step (2) to a silkworm excrement pool for composting, covering a layer of mulberry twig powder or rice bran with the thickness of 5-10 cm on the surface of the silkworm excrement during silkworm excrement composting, and composting for 15-30 days under an aerobic condition; during the period, water evaporation prevention measures are taken;
(4) application: applying the silkworm excrement fermented in the step (3) to sugarcane planting; the application method comprises the following steps:
A. newly planting sugarcane: applying the silkworm excrement obtained by fermentation in the step (3) as a base fertilizer to sugarcane seed stems according to the weight of 450-550 kg/mu;
B. perennial sugarcane: and (4) using the silkworm excrement fermented in the step (3) as spring fertilizer, and spreading the spring fertilizer among the rows according to the fertilizing amount of 450-550 kg/mu.
Wherein in the step (2), the beneficial microbial agent addition method comprises the following steps: uniformly mixing the beneficial microbial agent with the sweet and sour mixed liquid in equal mass ratio, standing for 25-40 min, and diluting by 700-900 times with water; spraying the mixed microbial liquid on the surface of silkworm excrement, moving out of the silkworm house, moving out of one surface, and uniformly stirring; controlling the water content of the silkworm excrement to be 50-60%, and when the water content of the silkworm excrement is less than 50%, adding clear water to ensure that the water content of the silkworm excrement is between 50-60%.
Wherein, in the step (3), the retting and fermenting time is 20-30 days in spring and autumn and 15-20 days in summer.
Wherein the mixing mass ratio of the beneficial microbial agent to the mixed liquid of sugar and vinegar is 1: 1: 1.
wherein the beneficial microbial agent consists of photosynthetic bacteria, lactic acid bacteria, saccharomycetes, actinomycetes and fermentation system filamentous bacteria.
Wherein the effective chlorine content of the bleaching powder solution is 0.30-0.45%.
In the step (4), the newly planted sugarcane and the perennial sugarcane are fertilized by silkworm excrement bio-organic fertilizer, and the fertilizing amount of the newly planted sugarcane and the perennial sugarcane is 75-100 kg/mu.
The silkworm excrement bio-organic fertilizer adopted by the invention is preferably a silkworm excrement bio-organic fertilizer which is produced by commercial Guangdong plant dragon biotechnology limited company and is 'Tianbuyu'.
Compared with the prior art, the invention has the following beneficial effects:
1. compared with the traditional method for preventing and treating the sugarcane borers, the method has the advantages of no toxic or side effect, no pesticide residue, no hormone addition, no heavy metal and harmful germ pollution, environmental protection and environmental protection; the method has the advantages of simple process and high production efficiency, can prevent and control pests, can be used as an organic fertilizer to provide nutrients for sugarcane, and can increase the soil fertility, thereby achieving the purpose of zero application of pesticide and chemical fertilizer.
2. The invention has remarkable effect of preventing and treating sugarcane borers. The test was carried out on the bridge ballast of the Xingbang area, and the effect is very obvious. The worm-saving rate is 0, compared with the existing chemical pesticide, the prevention and control are reduced by more than 10.45%, the sugarcane seedling production has good growth vigor and more effective stems, the germination rate is improved by 6.57%, the tillering rate is improved by 7.28%, the dead center rate is reduced by 23.01%, and the yield is increased by 15.01%.
