Description

Direct seeding machine herbicide sprinkler

Technical Field

The utility model relates to the field of agricultural machinery, especially, relate to a direct seeder herbicide sprinkler.

background

At present, the rice planting mode in China is mainly machine direct seeding. The direct seeding machine becomes the trend of the mechanical rice planting technology by virtue of the characteristics of labor saving, low cost, high yield, high adaptability and the like.

in recent years, no-tillage direct-seeding cultivation of rice is rapidly developed. The method has the advantages of saving time, saving labor, saving energy, protecting environment and being easy to manage, improving physical properties of soil, field ventilation conditions and enhancing root activity by no-tillage direct seeding of rice, having good effects on increasing the yield and income of rice and being widely recognized by rice planters. However, direct seeding of rice has some problems, and the growing environment of straight rice fields is also suitable for the growth of weeds due to the requirement of early growth of rice seeds, thereby influencing the growth and development of crops. In dealing with weed problems, the method of spraying the herbicide is generally adopted, and most of the sprayed herbicide is after rice is subjected to a transplanting operation. Most farmers currently choose herbicides to weed the paddy field because they reduce their physical labor and increase the yield of rice.

Herbicides, which are both advantageous and have their own drawbacks, have a certain toxicity and can cause a certain damage to the surrounding environment as chemical agents. If the herbicide is sprayed too little, the weeding effect is not obvious, so that weeds rob the growth nutrients of rice, if the herbicide is sprayed too much, crops can partially absorb the herbicide, the growth of crops such as rice can be influenced, chemical substances are rich in farmlands, and when water in the farmlands flows into other places, the ecological environment can be polluted, so that the spraying amount of the herbicide needs to be accurately controlled, and the method has important significance.

At present, spraying devices of domestic and foreign direct seeding machines mainly spray liquid to atomize the liquid, but when the direct seeding machines are used for transplanting rice seedlings, if the direct seeding machines are liquid herbicides, the direct seeding machines can be further diluted by water, so that the solid herbicides have certain advantages in keeping the timeliness.
