Embodiment 1

[0012] Potato micro spraying band irrigation antifreeze method, it carries out according to the following steps:

[0013] 1) Production of the micro-spray belt: directly process the water outlet holes on the flattenable plastic hose by mechanical or laser;

[0014] 2) Arrangement of micro-spray belts: Arrange micro-spray belts in the field. The ground for laying porous micro-spray belts should be flat. In mountainous areas or slopes, micro-spray belts should be laid according to contour lines. The micro-spray belts should be laid flat on the ground. And pay attention to make the water outlet upward, and fix it properly with iron wire if necessary;

[0015] 3) The leaves of the potatoes are sprayed with water using a micro-spray belt.

[0016] Further, the time for spraying water in step 3) should be the second day after frost occurs.

[0017] The working principle of the micro-spray belt: The micro-spray belt is also called porous tube, water spray belt, sprinkler belt, and ...

Abstract

The invention relates to the technical field of agricultural planting, in particular to a micro-spraying hose irrigating and freeze preventing method for potatoes.The method comprises the following steps that 1, micro-spraying hoses are manufactured; 2, the micro-spraying hoses are arranged; 3, water is sprayed on leaves of the potatoes through the micro-spraying hoses.Compared with fertilizer adding and applying, film covering and the like, the micro-spraying hoses can be repeatedly used, and therefore the freeze preventing cost of the potatoes is lowered; in addition, the sprayed water washes off frost on the leaf surfaces, therefore, the better and more direct freeze preventing effect is achieved, the labor intensity is lowered, and the labor cost is reduced; freeze preventing consumes a large amount of labor force compared with the measures such as fertilizer applying and film covering due to the fact that the potato planting area is large, and through micro-spraying hose irrigating and freeze preventing, the labor force requirement can be lowered, and the cost can be saved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a micro-spray belt irrigation antifreeze method for potatoes. Background technique [0002] Potato is an important grain, vegetable, feed crop and industrial raw material. It is one of the five staple foods in China. It has high nutritional value, strong adaptability and large output. It is the third most important food crop in the world, second only to wheat and corn. . Potatoes are cold-loving crops and are low-temperature crops. The formation and growth of its underground tubers requires a loose, airy, cool and moist soil environment. Temperature requirements: The optimum temperature for tuber growth is 16°C-18°C. When the local temperature is higher than 25°C, the tuber will stop growing; the optimum temperature for stem and leaf growth is 15°C-25°C, and it will stop growing if it exceeds 39°C. Potatoes can be cultivated in multiple seasons, including spring ...
