Embodiment 1

[0041] An ecological control method for rice leaf rollers and stem borers. Ducks and chickens are stocked in paddy fields for pest control. From the rice seedling stage, 10 ducklings with a body weight of 150g / are stocked per acre of paddy field. At the same time, per acre of paddy field Stock 12 chickens aged 65 days and weighing 1.0kg / piece. The stocking time is from 6:30 to 18:30 every day, until the ducks and chickens can be sold. The specific control methods include the following steps:

[0042] (1) seedling stage: after paddy rice cultivation 8d, duck and chicken are put in a suitable place to breed in the paddy field every day, adopt seedling-strengthening agent, seed-dressing agent and the method of sending grafting medicine simultaneously to prevent and control diseases and insect pests; Described seedling-strengthening agent method is every mu of seedling field Seedling-strengthening agent 15kg, wherein 10kg is sprinkled on the furrow surface, and 5kg is sprinkled in ...

Embodiment 2

[0048] An ecological control method for rice leaf rollers and stem borers. Ducks and chickens are stocked in paddy fields for pest control. From the rice seedling stage, 12 ducklings with a body weight of 200g / are stocked per mu of paddy field. Stock up 14 chickens with a weight of 1.5kg / 75 days, and the stocking time is from 6:30 to 18:30 every day, until the ducks and chickens can be sold. The specific control methods include the following steps:

[0049] (1) seedling stage: after paddy rice cultivation 12d, duck and chicken are put in a suitable place to breed in the paddy field every day, adopt seedling-strengthening agent, seed-dressing agent and the method of grafting medicine simultaneously to prevent and treat diseases and insect pests; Described seedling-strengthening agent method is every mu of rice seedling field Seedling-strengthening agent 15kg, wherein 10kg is sprinkled on the furrow surface, and 5kg is sprinkled in the hole of the seedling holder; the seed dressi...

Embodiment 3

[0055] An ecological control method for rice leaf rollers and stem borers. Ducks and chickens are stocked in paddy fields for pest control. From the rice seedling stage, 11 ducklings with a body weight of 170g / only are stocked per mu of paddy field. At the same time, every mu of paddy field Stock up 13 chickens with a weight of 1.3 kg / 70 days, and the stocking time is from 6:30 to 18:30 every day, until the ducks and chickens can be sold. The specific control methods include the following steps:

[0056](1) seedling stage: after paddy rice is cultivated 10d, duck and chicken are put in a suitable place to breed in the paddy field every day, adopt seedling-strengthening agent, seed-dressing agent and the method of grafting medicine simultaneously to prevent and treat diseases and insect pests; Seedling-strengthening agent 15kg, wherein 10kg is sprinkled on the furrow surface, and 5kg is sprinkled in the hole of the seedling holder; the seed dressing method is that every 2.5kg se...

Abstract

The invention relates to rice cnaphalocrocis medinalis and an ecological preventing and controlling method of stem borers. Ducks and chickens are stocked in a rice field to prevent and control insectpests, from the seedling stage of rice, the ducks and the chickens are stocked in the rice field every day, the stocking time is 6:30-18:30 every day, stocking is conducted till the ducks and the chickens can be sold, and the specific preventing and controlling method is implemented according to different stages of the rice. Preying habits of poultry are utilized to prevent and control the rice stem borers and cnephalocrocis medinalis so that the rice stem borers and the rice cnaphalocrocis medinalis can be effectively controlled, pesticide pollution is reduced, and the occurrence of large-area diseases and insects of the rice is effectively controlled and prevented; meanwhile, the utilization value of land is increased, the labor investment is reduced, the labor cost is lowered, production efficiency is improved, the quality and safety of the rice, the ducks and the chickens are high, no pesticide is left, the ecological environment pollution is effectively lowered, the rice yield permu can reach 10% or above, the yield is increased by 65-88 kg every mu, and the efficiency of effectively inhibiting diseases reaches 98.6% or above.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to an ecological control method for rice leaf rollers and stem borers. Background technique [0002] Borers and rice leaf rollers are important pests of rice in my country. Among them, the most common occurrence and damage of rice stem borers are the rice stem borer, the three stem borers and the rice borer. The occurrence of stem borers and rice leaf rollers generally leads to rice yield reduction10 % to 50%, the outbreak of pests may lead to the failure of rice harvest. For this reason, pesticide control is generally used in production, but pesticide control will pollute the environment and affect the quality of rice, and it is easy to make pests resistant to pesticides; while traditional ecological control is to target a certain type or a certain level of pests, such as Ecological breeding techniques such as rice ducks and rice fish can only control pests 0.0-0.5...
