Cultivation techniques of Potato covered with Straw

The first is to choose a place to rectify the bed. Choose neutral or slightly acidic rice fields. It is better to leave a stake of 15cm to 20cm during rice harvest. Before sowing, delimit the border and open the ditch, with a width of 1.4 to 1.6 meters, a width of 20 to 30 centimeters and a depth of 15 to 20 centimeters. The soil dug up during the trench should be thrown evenly in the middle of the border, and the surface of the border should be arched to facilitate drainage.

The second is seed potato treatment. Choose virus-free potato species with no disease and insect pests, smooth and fresh skin and a single weight of more than 20 grams. Before sowing, the seed potato was cut into 2-4 pieces according to the distribution of the bud eye and the size of the potato. Soak the cut potato pieces in carbendazim solution for 3-5 minutes. Spread out and dry the surface water. Mix the seeds with plant ash.

Third, sowing and fertilization. Generally, each row is 4 to 5 rows, the row spacing is 30 to 40 centimeters, the plant spacing is 20 to 30 centimeters, and there are 4500 to 5500 plants per mu. Press the seed potato a little hard when sowing so that the bud eyes are in full contact with the soil.

After sowing, the seed potato was covered with rotten farm manure, and N, P and K ternary compound fertilizer was sprinkled between rows. Chemical fertilizer should be applied between rows 6cm away from seed potato to prevent direct contact between chemical fertilizer and seed potato to cause seedling injury. Fourth, grass cover and water management. After sowing, straw is used to cover the border evenly, with a thickness of 8 cm to 10 cm. After covering the grass, clear the ditch and press the soil evenly on the straw. Adequate moisture must be ensured during the growth and development of potatoes. In case of drought, small water should be used to irrigate the furrow, so that the water can slowly seep into the border and should not be irrigated by flood. Attention should be paid to drainage and waterproofing in rainy season or low-lying plots. Fifth, pest prevention and control. Potato is prone to late blight, bacterial wilt, ring rot, early blight and aphids and other diseases and insect pests, attention should be paid to control. Sixth, timely harvest. When the stems and leaves are yellow, it indicates that the potato pieces are ripe and can be harvested. Pluck away the straw and pick up the potatoes.
