Large-ridge and double-line under-film drip-irrigation water-saving cultivation method of winter and early spring potatoes

Abstract

The invention discloses a large-ridge and double-line under-film drip-irrigation water-saving cultivation method of winter and early spring potatoes. The method comprises the following steps of (1) potato seed selection and treatment, (2) seeding, (3) drip-irrigation equipment laying and plastic film mulching, and (4) field management. The cultivation method is a water-saving irrigation technology combining a large-ridge and double-line technology, a plastic film mulching technology and a drip-irrigation technology organically, has a particularly remarkable effect in arid and semi-arid regions, integrates the edge line advantage, maintenance of the optimum water content of root regions, effective improvement of the ground temperature, evaporation suppression and water saving, has the characteristics of preserving soil moisture, maintaining fertilizers, keeping warm, remarkably improving utilization of optical energy, water and the fertilizers, saving the water, saving labor, increasing a yield and improving the efficiency, and has the advantages of saving the water and the labor, increasing the yield and improving the efficiency.

Description

technical field

[0001] The invention relates to the technical field of crop planting and agronomy, in particular to a method for drip irrigation and water-saving cultivation of potatoes in large ridges in winter and early spring with double rows of film. Background technique

[0002] Potatoes are not only food crops, but also economic crops, which are widely grown all over the world. The development of southwestern winter and early spring potatoes can not only increase the multiple cropping index and increase the total grain output, but also fill the gap in the northern potato supply, which is of great significance to further ensuring national food security and increasing farmers' income. In recent years, winter and early spring potatoes have developed rapidly in the southern region, and have been identified by the Ministry of Agriculture as key areas for future potato development in China. However, in the past three years, there have been severe autumn, winter and spring d...

[0025] (1) Selection and treatment of seed potatoes: select virus-free seed potatoes of excellent varieties with a growth period of about 75 to 90 days, strong stress resistance, good potato shape, shallow bud eyes, and high commercial rate. Cut the potato pieces larger than 75g into pieces 2 to 3 days before sowing. Each piece should contain 2 bud eyes. After cutting the potato seeds, add gypsum powder, streptomycin and carbendazim for three times. The ratio is: 90:5:5, uniform seed dressing, and the ratio of medicinal potato is 1.5:100, and spread to dry to heal the wound;

[0026] (2) Sowing was completed at the beginning of January. When sowing, a large ridge double-row pattern was adopted. Ditching can be done manually or by animal power. The ridge spacing is 1.1m, the large row spacing is 70cm, and the small row spacing is 40cm. Two rows of potatoes are planted on the ridge, and the plant spacing is 30cm. Then, after the seed potatoes are placed, apply farmyard manure, ...
