Application condition of sprinkler irrigation equipment in vegetable cultivation

A lot of people think that sprinkler irrigation is only for agriculture, for lawn irrigation. In fact, sprinkler irrigation equipment can also be used in watermelon, vegetable cultivation.

In recent years, with the development of sprinkler irrigation equipment and technology, it has the advantages of saving water, saving labor, saving fertilizer and improving yield, etc., and the application effect is very obvious in large slope land, dry land and tidal flat seasonal land. Next, let's look at the use conditions of sprinkler irrigation equipment in vegetable cultivation.

Application conditions of sprinkler irrigation equipment in vegetable cultivation:

1. The selected land is large and flat, generally 1.33 ~ 6.67 hectares. Too small land and too complicated terrain will increase the investment cost, the larger the land, the more materials will be saved.

2. The water source should be within 500m from the land parcel. If it is in the alpine base with an altitude of 800-1600m, the secondary water supply method can be applied to solve the problem.

3. The cultivation area of this technology is large and the quantity of products is large, so it should be in the land with convenient transportation, which is conducive to the mechanical transportation of products.

4, in small green vegetables, amaranth, Chinese cabbage heart and other leafy vegetables on the application effect is not very good.

Application technology of sprinkler irrigation equipment:

When starting the water spraying, 15 ~ 20 pairs of gate valves should be opened first. The specific number is determined according to the water pressure. Each spray should be changed once for 20 ~ 30min.

If fertilization is needed, especially compound fertilizer or phosphate fertilizer, it should be soaked and filtered in the first day, loaded in a larger container in proportion with a certain amount of water, put the hose at the water inlet of the pump, and open the gate valve to send fertilizer along with the water. Calculate how much fertilizer to use in one field and mix it in another. When installing the water pump, the water source of the water pump should be isolated with gauze, and the water pump basket should also be wrapped with gauze, and then put a bamboo basket of isolation sand below to avoid blocking the spray pipe.

For a long time, the water outlet of the sprinkler belt is blocked. When spraying water, open the front end of the sprinkler belt to wash the sand, or while spraying water, while tapping the spray belt with a wooden stick. When receiving the sprinkler belt, it should first take off the one end connected to the four, roll and pull at one end, roll into a pie shape and paste with adhesive tape, so as not to discount and save time for the next time.
