Problems solved by technology

[0002] Conventional rice farming relies on chemical agents to control pests and diseases to obtain high and stable rice yields. However, the large-scale application of chemical agents not only kills the target pests and diseases, but also kills the beneficial natural enemies in the rice fields, reduces the biodiversity of rice fields, and pollutes the The farmland environment increases the amount of pesticide residues in rice, which is not conducive to the green and organic production of rice, but also seriously restricts the sustainable development of rice cultivation

Embodiment 1

[0032] This embodiment is carried out through the following steps.

[0033] (1) Raising seedlings and raising ducks: The rice used in this example is Meixiangzhan with high yield and strong lodging resistance. Generally, about 3 days before sowing, choose fine weather and dry the seeds for 4 hours. During the drying, they should be turned frequently to make the seeds dry. Consistent, and then carry out seed soaking, disinfection and germination treatment. Seed soaking: After washing the seeds with clean water, pre-soak them with clean water for 12 hours. During the period, change the water every 4 hours to germinate the germ spores on the seeds; disinfection: soak the seeds in 300 times strong chlorine solution for 12 hours, and the disinfection solution is one inch above the surface of the seeds (do not change the water during disinfection), after disinfection Rinse the residual liquid repeatedly with clean water. After washing, put it in clean water and continue to soak th...

Abstract

The invention relates to a method for continuously controlling insect pests and weeds of field quarter paddy through intercropping two batches of ducks. Ten days before the first batch of ducks are freed in the field, the second batch of ducklings are bred so as to substitute the first batch of ducks to control the insect pests and weeds, and the two batches of ducks cohabitate in the paddy field for about 10 days and are kept during the period from a paddy seedling establishment period to a mature period all the time. Under the condition of no control methods of pesticide and herbicide application, after the method is adopted, both the insect pests and weeds can be obviously reduced from the seedling establishment period to the mature period of paddy planting, so that a function of continuously controlling the insect pests and weeds of the paddy is exerted during all the process, the paddy yield can be increased, two batches of ducks are bred through one quarter paddy planting season, and the economic benefit is higher than conventional duck and paddy co-production.

Description

technical field [0001] The invention relates to the technical field of environment-friendly prevention and control of diseases, insect pests and weeds, in particular to a method for continuously controlling diseases, insect pests and weeds by raising two batches of ducks in one season of rice in the field. Background technique [0002] Conventional rice farming relies on chemical agents to control pests and diseases to obtain high and stable rice yields. However, the large-scale application of chemical agents not only kills the target pests and diseases, but also kills the beneficial natural enemies in the rice fields, reduces the biodiversity of rice fields, and pollutes the The farmland environment increases the amount of pesticide residues in rice, which is not conducive to the green and organic production of rice, but also seriously restricts the sustainable development of rice cultivation. Duck-rice co-cropping is an eco-environmental and environmental-friendly comprehe...
