Abstract

The invention provides a method for preventing and controlling injurious insects of organic rice by Chinaberry water decoction. The method is characterized by comprising the following steps of: (1) preparing a mixture by blending Chinaberry bark, leaves and fruits with a mass ratio of the bark to the leaves to the fruits being 1 to 1 to 0.2, smashing the mixture, and adding water into the mixture with a mass ratio of the water to the mixture being 10-12 to 1 in a container to be decocted; (2) continuously decocting the mixture in the water for 50-60 minutes, fishing sticks and residues of the Chinaberry water decoction, cooling the decoction, and filtering the decoction to obtain Chinaberry water liquor; and (3) using the liquor in a certain dosage: uniformly spraying 4-5.5 kg of the prepared Chinaberry water liquor which is blended with 40-55 kg of water to seedling leaves per mu in the first ten days or the middle ten days of June and the first and middle ten days or the last ten days of July. The method can be used for fully replacing chemically synthesized insecticides and is free of pollution and residues and is environmental-friendly and safe. Raw materials are local materials and wastes are turned into wealth, so that much money is saved and the method is economical and practical. The method opens up a biological preventing and controlling path of plant diseases and insect pests of organic rice and maintains the quality and taste of the organic rice.

Description

A kind of method of China tree water cooking liquid prevention and control organic paddy rice insect

Technical field

The present invention relates to a kind of method of preventing and treating organic rice insect, particularly a kind of method utilizing China tree water cooking liquid prevention and control organic paddy rice insect.

Background technology

Organic rice is in ecosystem environment, from breeding to field planting, do not use chemical fertilizer, agricultural chemicals, all adopts microorganism, plant, animal to prevent and treat the integrated control that the method combined carries out disease worm, produce the pollution-free food that rice belongs to highest standard in the world.Organic rice adopts agriculture natural means to carry out appropriate managerial to the ecotope in rice field, as: select the measures such as disease-resistant variety, fertilizing soil, artificial weeding, control the harm reducing Pest organism effectively, be the basis of during organic rice is produced, pest being carried out to integrated control, also will prohibit the use chemosynthesis material and transgenic engineering product simultaneously.So organic rice need ensure with without the insecticide of chemosynthesis except insect pest, reach pollution-free, noresidue, environmental protection and the standard of safety.

Summary of the invention

In order to solve organic rice except insect pest without chemosynthesis insecticide, ensure its pollution-free, noresidue, the present invention proposes a kind of method of China tree water cooking liquid prevention and control organic paddy rice insect.

Technical scheme of the present invention is: a kind of method of China tree water cooking liquid prevention and control organic paddy rice insect, is characterized in that: described method comprises following steps:

1, amargosa, blade and fruit are mixed make mixture according to mass ratio 1:1:0.2 together, pulverized, decoct for the ratio of 1:10-12 adds water in container in mass ratio;

2, continue to decoct 50-60 minutes, cool cold after China tree water cooking liquid is skimmed bar slag, filter to obtain China tree water liquid;

3, usage and consumption: every mu, with China tree water liquid 4-5.5 ㎏ produced, is watered 40-55 ㎏ in early June or the middle ten days, and July early and middle ten days or the last ten-days period even spraying on seedling leaf.

To the further improvement of technique scheme be: the filter method in described step 2 uses nylon net filter.

Beneficial effect

China tree liquid of the present invention is amargosa, leaf, fruit add water the hydrate soln decocted; Folk tradition lumbricide, taste is special bitter.Main chemical compositions margosine, alkaloid, naphthols etc.To various pests, there is obvious Antifeedant Effects, rear three steps (chewing first, swallow and continue to take food) in pests process 4 step (to identification and the location of host, chewing first, swallow and continue to take food) be suppressed and do not take food cause it to die of hunger completely, reaching the object of pest control.This method can substituted chemistry synthetic pesticide completely, without and pollute, noresidue, Environmental Safety; And raw material is also gathered materials on the spot, turn waste into wealth, money, economy need not be spent more practical again, open the biological prevention and control approach of organic rice damage by disease and insect, keep the quality taste of organic rice.

Embodiment

A method for China tree water cooking liquid prevention and control organic paddy rice insect, is characterized in that: described method comprises following steps:

Specific embodiment one:

1, amargosa 5kg, China tree blade 5kg and 1kg fruit are mixed, cut up with a hay cutter into trifle and use mechanical crushing again, in mass ratio for the ratio of the 1:10 110kg that adds water decocts in metal bucket;

2, continue to decoct 50 minutes, cool cold after skimming bar slag, with nylon net filter China tree water liquid;

3, usage and consumption: every mu with China tree water liquid 4 ㎏ produced, be watered 40 ㎏ early June and July early and middle ten days even spraying on seedling leaf.

Specific embodiment two:

1, amargosa 5kg, China tree blade 5kg and 1kg fruit are mixed, cut up with a hay cutter into trifle and use mechanical crushing again, in mass ratio for the ratio of the 1:12 132kg that adds water decocts in metal bucket;

2, continue to decoct 60 minutes, cool cold after skimming bar slag, with double-layer nylon net filtration China tree water liquid;

3, usage and consumption: every mu with China tree water liquid 5 ㎏ produced, be watered 50 ㎏ early June and July early and middle ten days even spraying on seedling leaf

Filtering in described step 2 is use double-layer nylon net filtration, and the liquid after filtration is more easily used, and residue content is few, is optimum filtration method.

Claims

1. a method for China tree water cooking liquid prevention and control organic paddy rice insect, is characterized in that: described method comprises following steps:

(1) amargosa, blade and fruit are mixed make mixture according to mass ratio 1:1:0.2 together, pulverized, decoct for the ratio of 1:10-12 adds water in container in mass ratio;

(2) continue to decoct 50-60 minutes, cool cold after China tree water cooking liquid is skimmed bar slag, filter to obtain China tree water liquid;

(3) usage and consumption: every mu, with China tree water liquid 4-5.5 ㎏ produced, is watered 40-55 ㎏ in early June or the middle ten days, and July early and middle ten days or the last ten-days period even spraying on seedling leaf.

2. the method for a kind of China tree water cooking liquid prevention and control organic paddy rice insect according to claim 1, is characterized in that: the filter method of described step (2) uses nylon net filter.
