How to choose a suitable sprinkler according to different regions and different crops?

In order to make full use of the techniques of water-saving irrigation and soil water conservation, a variety of sprinkler irrigation equipment have been launched on the market to increase grain yield, but the sprinkler irrigation equipment used for different crops is also different in different areas. so how to choose suitable sprinkler irrigation machines according to different regions and different crops?

The irrigation technology and drip irrigation technology of reel sprinkler should be popularized.

The reel sprinkler irrigation technology is suitable for wheat, corn, soybeans, vegetables, potatoes, cotton, sugarcane, forage and other closely planted crops. At the same time, it can be tested, popularized and applied to rice. The investment of domestic machine mu is about 550 yuan / mu, the life span is 2030 years, the degree of automation is high, the labor cost is low, and the production efficiency is high. The water use efficiency is about 15% lower than that of drip irrigation, so it is not suitable for areas with extremely tired water resources. Limited by the terrain, it is not suitable for the mountains.

Drip irrigation technology is mainly used in cash crops, wide-spaced crops, such as vegetables, cotton, fruit trees (grapes, apples, pears, dates, bananas, etc.), seedlings and so on. Field crops are not suitable for drip irrigation, but can be considered in areas with extremely poor water resources.

Drip irrigation pipes for many years should be used for irrigation of fruit trees, with an investment of about 800 to 1000 yuan per mu. Drip irrigation belt for vegetables and cotton should be used once a year, with an investment of about 300,500 yuan per mu, of which the annual cost of replacing drip irrigation belt is only about 150 yuan.

Drip irrigation technology should be combined with irrigation and fertilization, which can reduce labor costs, save water consumption and fertilizer application, and improve the degree of integration of water and fertilizer.

Rational selection and scientific planning of high-efficiency water-saving technology

The reel sprinkler should be used for corn, and it should be popularized in water shortage areas.

Lin Guo: mainly distributed in South China, East China, Northwest, Southwest, North China and other producing areas, strive to stabilize the area at about 170 million mu, suitable for the promotion of drip irrigation, micro-spraying and other technologies.

Seedlings: mainly distributed in Huang-Huai-Hai, the middle and lower reaches of the Yangtze River, South China, covering an area of more than 14 million mu, suitable to popularize the comprehensive technology of sprinkler irrigation and micro-irrigation.

Vegetables: winter and spring vegetable bases in South China and the middle and upper reaches of the Yangtze River, summer and autumn vegetable bases in the Loess Plateau and southwest, facility vegetable bases in Huang-Huai-Hai and Bohai Rim, and out-of-season vegetable bases in South China such as Hainan and Guangxi. It is suitable to popularize reel sprinkler and drip irrigation technology.

Potato: mainly distributed in the Northeast, North China, Northwest, Southwest, South China and other five dominant producing areas, suitable for reel sprinkler or drip irrigation technology.

Cotton: mainly distributed in Xinjiang, Hebei, Henan, Shandong, Anhui and other areas, suitable for drip irrigation or reel sprinkler.
