A concave micro-ridge film-covered spot water seeder suitable for watermelon planting in dry and alkaline land

Abstract

The invention relates to the technical field of agricultural planting, in particular to a concave-shaped micro-ridge film-coated water point seeder suitable for planting watermelons in drought-alkali land; it can effectively increase the ground temperature and effectively avoid the occurrence of low-temperature rotten seeds and freezing damage to seedlings; By pointing water, the limited water can be fully utilized, which can effectively restrain and decompose the salt that moves upwards, and ensure the normal germination of watermelon seeds and the growth of seedlings. There are ridging devices, seeding devices, water pointing devices and film covering devices from left to right; the ridging devices include ridging plows set opposite to each other and a scraping plate arranged between the two ridging plows, the bottom end of the scraping plate There is a small scraper in the middle; the sowing device includes a storage bin, a sowing standpipe, a transmission device, a housing, a rotating shaft and a material distribution cylinder; the water pointing device includes a water tank, a connecting pipe and a regulating water valve; Shaft, two sets of pressure rollers and two sets of covering discs.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a concave micro-ridge film-covered water point seeder suitable for planting watermelons in dry-alkali land. Background technique [0002] There are large areas of saline-alkali land in my country. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, and the area of ​​saline-alkali land in my country is as high as 99.13 million hectares. Among them, coastal saline-alkali land is an important type of saline-alkali land in my country, with a coastline of more than 18,000 kilometers and a relatively wide distribution. Drought and saline-alkali has become an important factor restricting the development of agriculture. With the rapid development of urbanization in our country, the area of ​​cultivated land has been decreasing. Therefore, it is urgent to develop and utilize the vast saline-alkal...

Problems solved by technology

[0004] At present, the production of watermelon in the dry and saline-alkaline open field mainly adopts the planting procedures of digging holes, watering, sowing, covering soil, and covering film. , the ground temperature cannot be effectively increased, and low-temperature rotten seeds or seedlings are prone to freezing damage after sowing; (2) Due to the high salt content of groundwater in dry land saline-alkali areas, it cannot be directly used for planting irrigation, and there is basically no artificial irrigation conditions in this area, and it is completely dependent on Natural rainfall, but watermelon sowing in the open field in early spring requires a certain amount of humidity for seed germination and seedling growth. Using the existing watering method not only consumes a lot of water, it is easy to reduce the ground temperature, and the labor input cost is high; (3) due to the soil content in this area The amount of salt is high, especially in the early spring sowing season, which is dry and less rainy, and the soil returns to salt seriously. For flat border sowing, the salt that moves up cannot be effectively suppressed and decomposed, which directly affects the germination of watermelon seeds and the growth of seedlings.
