Description

Technical Field

[0001] The utility model relates to rapeseed planting equipment, in particular to an integrated machine for protective tillage and sowing and chemical control of rapeseed. Background Art

[0002] Rapeseed is an important oil crop in my country and has multiple uses such as vegetable, feed, and fertilizer. 80% of the planting areas are distributed in the middle and lower reaches of the Yangtze River. The planting pattern in the middle and lower reaches of the Yangtze River is mainly based on rice-oil rotation with alternating floods and droughts. Rapeseed direct seeding has the advantages of saving costs and labor. In recent years, the proportion of rapeseed direct seeding has increased year by year, while the proportion of transplanting has decreased year by year. However, there are also the following problems in the production of rapeseed direct seeding machinery.

[0003] 1. Due to the compaction of paddy field soil, the previous rice stubble is high on the surface, and the amount of straw left is large, which makes the rotary tillage parts easy to entangle and the straw coverage rate is low, causing the deep fertilizer shovel to be easily clogged by grass, and the working box surface is not flat, making it difficult to achieve deep fertilization operation;

[0004] Second, the seedbed preparation quality is not high. The rice straw is suspended in the air, which causes some seeds to be sown too shallowly and not touch the soil. The seeds cannot absorb water and cannot meet the germination conditions, which reduces the rapeseed germination rate and quality to a certain extent.

[0005] 3. There are many types of weeds in direct-seeded rapeseed, with a large base number, making it difficult to control, which restricts the high yield and efficiency of direct-seeded rapeseed. Among them, pre-winter weeds in rapeseed fields account for 70% to 80% of the total weeds in the entire growing season of rapeseed, and they have a great impact on seedling growth and later grain yield by competing for resources such as light, soil nutrients and water. Utility Model Content

[0006] In order to overcome the defects of the prior art, a rapeseed protective tillage and chemical control integrated machine is provided to solve the problems of low seed bed preparation quality and difficult weed control in the existing rapeseed direct seeding machinery.
