First, the election. The principle requirement is that it is not susceptible to drought, and it can be discharged in the event of rain. Can not be used before as a land plant for Solanaceae crops or root crops. Second, seed treatment. 10 to 15 days in advance. Pick out the rot tuber first. 1, cut the block. Before cutting, whole potatoes are soaked in 0.1-0.15% potassium permanganate solution for 10 minutes. Then the large seed potatoes are cut into several pieces, each weighing 30-40 grams, with 2 or more buds, and less than 50 grams of potato. Cut out. 2, disease prevention and disinfection. Cut the knives to pay attention to disinfection, cutting after cutting with a plant ash, cutting seed potatoes can be used streptomycin or carbendazim spray disinfection, and then set the cold dry incision hardened to scab. The diseased potato is removed. 3, germination. Sand beds are commonly used for germination, and the humidity of the sand is controlled so that the water does not seep out of the ground. Seed germination after germination, in particular, should pay attention to gently, carefully handling, try to avoid breaking the seed buds. Third, the site preparation. When harvesting late rice, harvest it as close as possible, leaving no earthworms. After the late rice is harvested, the soil is immediately set, and it is only necessary to split the ditch without plowing. The width of the surface is 1.6 meters. Each side has a deep groove of 35 centimeters in width and 20 centimeters in depth. It is used as a work and drainage ditch; the other side is opened with a shallow ditch, which is 30 centimeters wide and 7 centimeters deep. Before planting, open the field side trenches and deep trenches, and leave shallow trenches for reopening. Fourth, planting. Before the planting, put the horse water moist wet potato. Planting potatoes in rows of 40 cm in spacing, 30 cm in spacing, and 20 cm in rows from the ditch. Seeds of potato sprouts are directed downward or sideward, and the incision surface is not downward. About 4,500 acres of sowing potatoes, can be used to cover the seeds of small pieces of mud. After the planting, the total N, P and K are 15% potassium sulfate compound fertilizer 60-75 kilograms, and one-time basal fertilizer is evenly applied to the sides of the rows next to the seed potatoes, and the conditions can be added to the maturity of the fertilizer or soil. Mixed fertilizer, pay attention to the use of pig manure to fully decomposed, and can not contact with seed potatoes. Fifth, straw cover. After the seedlings are fully covered with straw 7-8 cm, 750 kg straw per acre (that is, about 2 acres per acre straw). The thickness of the cover is the degree of opacity on the face. Note that the straw should be evenly covered and covered on both sides of the beak. After the straw is covered, open the shallow ditch and deep ditch, and use the soil to press the straw at several points; it is not necessary to evenly cover the surface and press the mud too much. Then set the grass and water to be sprayed, with the degree of wetness of the straw, the general requirement to shower 2-3 days. Six, field management. 1. Dry and whitish soil in front of the drought-tolerated plant, which can be drained by flooding, drained or drained after artificially immersing in wet mud, or wet straw and soil on the day after planting (must be the same day). The seedlings are entangled with rice straw, and straws can be pulled out with wooden sticks to speed up seedlings. Fertility is generally no longer fertilized, in case of a long clear and no rain, we must timely irrigation ditch water penetration and wet, but in case of rainy weather should pay attention to clear drain drainage. 2. Pests and diseases mainly include late blight, stalk rot, aphids, and ground tigers. They can be controlled by using mancozeb, chlorothalonil, thiophanate-methyl, trehaloxime, Dagongchen, farmland, and other pesticides. Seven, prevent frost. On the evening before the onset of frost, trees can be used to apply foliar or covered with straw or burn grass. Eight, harvest. There is no need to use shovels to dig the potatoes. Some potatoes can be picked just by opening the straw, and some must be lightly digged with bamboo sticks.
