The potato cultivation time is the best time for cultivating crops in the spring months of January and March. It chooses sandy loam with rich organic matter, 1500-2000 kilograms of organic fertilizer, 150 kilograms of turf ash, and fertilizes the soil with a rotary cultivator. Mixing, smashing, smashing, width 1.3 meters, three kinds of sorghum, row spacing 40 cm, spacing 25 cm, 100 kg per mu, species masking mulch. When seedlings break the film and induce seedlings in time, when the wheat seedling grows 15-20 centimeters, topdressing, 15-20 tens of methane manure water, and 7.5 kilograms of potash fertilizer are applied, then the soil is dipped in the bottom of the ditch to promote the early growth of the plant. Sprinkle water often, keep the soil moist, avoid being too wet or too dry. First, the choice of species Select disease-resistant species, pick healthy potatoes from disease-free fields, and pre-soak the potato seeds in warm water at 40°C-50°C for 1 minute, and then add them in warm water at 60°C (the ratio of seed and warm water is 1: 4) Soak for 15 minutes. Soak the seed potatoes with 72.2% Prec or 70% Kelu (800x) for 15 minutes and then dry the seeds. Second, soil disinfection In the case of potatoes grown in vegetable fields where yam and solanaceous fruits have been planted, severe soil disinfection must be carried out. The method is: first remove the stems and leaves of the former crop, deepen the soil by more than 20 cm, and then eradicate the residual roots (tubers) in the tillage layer to reduce pathogens. Use 50% carbendazim WP 2 kg of mixed lime 20 kg -30 kg per acre and 40 kg -60 kg of plant ash into the field. After cultivating and cultivating the ridges, cultivating the ridges, cultivating holes or ditches in the ridges, spreading 40% of pentachloronitrobenzene 3 kg and 90 kg-150 kg of dry fine soil around the potatoes when growing the potatoes. Third, fertilizer and water management About 20 days in advance, 300 kg to 500 kg of manure per acre will be evenly distributed between 25 kg and 50 kg. Ammonium bicarbonate is sealed and piled in the sunny place. When the seedlings grow 3 to 5 leaves, topdressing 1 times, in general, 500 times schizophyllum plus urea or potassium dihydrogen phosphate 1% plus bulking element, potato block enlargement period pay attention to strengthening the field irrigation to increase output value. Fourth, field management 1. Before emergence: The emphasis is on adding light to avoid wind, snow, and rain weather damaging the shed. 2, seedling period: cover up the plastic film, it is timely to artificially assist the rupture of membranes; open culturers, after rain or sprinkle water after the timely scratching, breaking the hard shell, so that the wheat seedlings unearthed smoothly, promote Miao Qi, Miao whole, Miao Zhuang. 3, hair tree period: After the potato out of the seedlings, the main target is to promote the growth of strong trees and build a shelf Fengdeng. The key to handling is to prevent drought or watering. When spraying, do not pass over the ridge roof and carry out cultivator and earth-cultivation. In the end, bred the shoulders of the group and build an outstanding tuberculosis condition. Large, medium, and small arch shelters should gradually increase the ventilation and ventilation time. After the "grain rain," the maintenance equipment can be revoked depending on the weather conditions. 4. Potato period: After the buds of the potato group bloom, they begin to form potatoes. By the flowering stage, the potatoes quickly expand quickly. At this time, the amount of watering should be added. The principle of watering is to keep the soil moist and not to form water in the field. This period should also pay attention to the prevention of pests and diseases, especially the potato disease, should be placed in the early prevention, to prevent the main, once the disease is difficult to control. During this period, if the plant has a phenomenon of leggy, artificial control should be carried out, and paclobutrazol (PP33) can be sprayed 1-2 times with a conversion concentration of 100 ppm. 5. Harvest period: Potatoes should be suspended from spraying 7-10 days before harvest. 1 Large, medium and small sheds can be sold in the morning market. The appropriate harvest time is before and after the May Day. 2 The cultivation of open field should allow them to grow in abundance, and a higher output value and a better standard of the tubers should achieve better results. The harvest time is suitable for the early June. canned rea bean , canned mung bean, canned grass jelly, canned chestnut, canned safflower bean, canned oats, canned purple rice, canned purple potato, canned taro,canned babao bean cereal can, canned goods, canned corn,tin can KARAK , https://www.jskarak.com
