Jiangxi rice no-tillage and throwing raft technology promotes the forefront of the country

The reporter learned from the on-site meeting of the province's rice-free no-tillage and throwing shovel technology held in Huichang County on August 29, this year, the area of ​​rice-free ploughing and dumping in the province reached more than 4 million mu, which was more than the beginning of 2002. 4.24 million mu has increased by nearly 100 times, ranking second in the country. According to the person in charge of the Provincial Agricultural Technology Extension Station, in the past six years, the province has promoted the area of ​​rice, no-tillage and dumping, surpassing 10 million mu, increasing the yield of rice by nearly 180,000 tons, and increasing the farmers' income by about 600 million yuan.
The rice-free tillage and throwing technique is a new rice cultivation technique. In the promotion, the agricultural departments at all levels have achieved “four combinations” through administrative promotion, demonstration driving, technology-driven, and project promotion: no-tillage combined with less tillage (rotary tillage), no-tillage combined with cover, improved varieties Combining with good law, combining agricultural machinery with agronomy, actively innovating agricultural technology promotion methods and methods, and extensively carrying out technological innovations in herbicides, fertilizing fertilizers, straw returning and farming models, overcoming no-tillage and throwing weeding Technical problems such as seedlings and years of no-tillage bring soil compaction, and find out no-till live, straw (green manure) returning to no-tillage, and “two exemptions and one less” (no-tillage of rapeseed, no-tillage of early rice, less tillage of late rice) ), lotus root - late rice, tobacco - late rice and other ecologically efficient technology models, to achieve rapid promotion of rice less no-tillage throwing technology.
The promotion of less no-tillage and throwing raft technology has achieved gratifying economic, social and ecological benefits. According to local estimates, the yield of rice no-tillage throwing is 3% higher than that of conventional tillage throwing, which is 7%-10% higher than that of ploughing. Compared with conventional tillage, no-tillage can block wind and sand, reduce runoff by 60%, reduce soil erosion by about 50%, increase soil water storage by 15%, save water by 50 to 60 cubic meters per acre, and reduce fertilizer and festival. The medicine is about 10%, saving 2 to 3 labors. After deducting the cost of herbicides and spraying, the income per mu can be increased by 50 to 70 yuan. At the same time, less tillage and throwing simplifies the operation procedure and alleviates the seasonal contradiction. Early rice planting period of 3 to 5 days solved the problem of farmers' ploughing, plucking and transplanting the "three bends", which created conditions for the transfer of rural labor to the secondary and tertiary industries.

Casting Iron Pump

1. Compact structure: The pump body and impeller are designed in one piece, which makes the pump more compact, occupies a small area and is easy to install and maintain.
2. Corrosion resistance: The pump body and impeller are made of high-strength cast iron with special treatment on the surface, which has excellent corrosion resistance.
3. High efficiency and energy saving: The impeller is made of high quality wear-resistant material, which has the feature of high efficiency and energy saving and can greatly reduce energy consumption.
4. Safe and reliable: There are multiple protection measures during the operation of the pump, such as overload protection, overheating protection, etc., which ensure the safe and reliable operation of the pump.
5. Wide application: cast iron pumps are suitable for various industrial fields, such as petroleum, chemical, pharmaceutical, food, textile, etc., and can convey various liquid media.
