How to plant a good vegetable type autumn potato
First, the selection of good seed potato must adopt the “Dongnong 303â€, which has wide adaptability, strong resilience, short growth period, rich nutrients, high yield, good quality, good taste and good taste, from the north. "Kexin 4" and so on. Second, appropriate sowing autumn potato sowing is the basis for high yield. Seeding is too early, the autumn volt is high, the disease resistance is poor, the growth is poor, and the yield is low. Sowing too late, lack of growth. In the later period, it is vulnerable to frost and the output is not high. The practice of many years of production shows that in the north of the plains of northern Zhejiang, planting is generally appropriate in late August, and harvesting will begin in mid-November. Because the sowing period is at a high temperature and a typhoon rainy season, seedlings should be planted in sunny evenings or on cloudy days in order to ensure full seedlings and seedlings. After planting, the rice straw should be covered with straw to prevent heavy rain and reduce soil temperature, so as to facilitate full seedling growth. seedling. Third, the germination planting Because the seed potato is harvested from spring potato, it should be treated with cold bed before planting. The selected potato pieces will be cut into small potato pieces with 2-3 buds. After washing with clean well water, the thin booths will be placed in a shaded and ventilated place for 1-2 days. After the incision is healed, germination will be carried out; The sand is used as a germination bed, and the seed potatoes are evenly discharged on the germination bed with the buds facing upwards, and it is advisable to not touch each other. Then a thin layer of fine soil is used as a barrier on the tuber, and up to 3 layers can be placed. Cover with moist fine soil to cover no seed potatoes for degree. Then cover with a layer of wet straw, in order to maintain the germination bed cool and moist, in order to facilitate sprouting, after 7-10 days, when the potato shoots length 2 cm removed, in the shade of thin booths spread light, to be broadcast. Fourth, rational close planting and reasonable close planting is the key technology for increasing planting (holes) and increasing potato production. The vegetable-type autumn potato is harvested and harvested. The harvest period is short and can be planted properly. General acres planted 6000 (points). For sorghum planting, increase the soil layer to facilitate drainage, increase the temperature difference between day and night, and promote the growth and development of potato. The sulcus is 1.2 meters wide, each row is planted with 2 rows and the spacing is 5018-20 cm. Fifth, scientific fertilization should be applied to the base fertilizer, early application of Miao Fei, increased P and K fertilizer. At the same time to do deep-rooted fertilizer, organic fertilizers and fertilizers can not be in direct contact with potato sprouts to prevent the rotten potato sprouts. General Mu Shishu shed pig manure 1500 kilograms, phosphate 30 kilograms, potash 10 kilograms, open a deep hole. After the emergence of Mu Shi pig manure 10 Tam, ammonium bicarbonate, potash 5 kg mixed with water pouring. During budding and flowering stages, phosphorus and potassium fertilizers are suitable depending on the growth conditions. It is necessary to prevent too much nitrogen fertilizer, stubborn stems and leaves, few potato crops, and low yield. Sixth, to strengthen management after the emergence of timely cultivation of loose soil, weeding fertilization, drainage and drainage work. During the seedling stage, underground pests, leafhoppers, and aphids are used to prevent stems and leaves, and in the later stages, virus diseases and ring rot are prevented. When the potato begins to bloom and grow potatoes, it is necessary to stop the cultivator, clear the ditch, and promote the development of large potatoes. China Agricultural Network Editor
