Walking water-saving irrigation technology
Walking-type water-saving irrigation technology is a technology that utilizes a large number of existing rural walking-type power machinery (a tractor or agricultural transport vehicle) equipped with a water-saving irrigation machine to perform irrigation operations while walking. Therefore, it is called a walking type festival. Water irrigation technology. This technology includes two technical contents: First, the sow planting technology, in the surrounding soil around the seed to increase waterlogging to protect the seed germination; Second, seedling irrigation technology, irrigation in the root area of ​​the soil to increase seedlings. Walking water-saving irrigation technology is based on the premise of water-saving, as far as possible the use of efficient local irrigation, a small amount of water in accordance with the demand of quantitative water accurately applied to the seed around the root zone or seedlings in the soil, reduce or avoid a variety of forms The waste of water can achieve the water-saving effect of drip irrigation, greatly improving the water utilization rate. Generally, the amount of water per mu is 1-4 cubic meters, which is more than 50% of water saving compared Flood irrigation more than 80%. At present, the main process for the sowing of water-saving mechanical irrigation sowing technology is to use a tractor to pull a trailer carrying a water tank and sow the rear part of the tractor. At the same time, watering and fertilizing operations are performed. The water pipe led from the water tank is connected with the water supply device of the seeder. It can realize a number of operations such as ditching, water application, fertilization, sowing and earth covering. If the soil moisture is not good, combined with water shortage at the seedling stage, the joint water-feeding and fertilizing operations can be performed. This technology not only makes full use of the power machinery such as tractors that have a large amount of rural ownership, but also improves the utilization rate of the existing power machinery. The matching planting equipment has a simple structure, multi-functionality, double operation, low cost, and can adapt to current farmers. Income level. It is a high-efficient water-saving technology that solves the problem of spring drought seeding, seedling failure, and seedling maintenance. It is a practical technology for ensuring food production and an important means for developing the rural economy and solving the problem of increasing farmers' income in drought-stricken areas. It is particularly suitable for Water scarcity frequent drought areas.
