The processing of potatoes is done by selecting chips that match the characteristics of the species, are free from disease and pests, are free from frost, are skin-skin-skin smooth, and are tectonic. Some 35 days before seeding, warm sprouts in a dark and warm environment of around 20°c, and tan sprouts 10-15 days later when the top sprouts grow to about 1 cm. Placing the seeding of potatoes in an environment around 15°c makes it greener. Scratch chips in the clear and cool mornings or evenings in the cold air. Slicing is done with 65 per cent alcohol, which is then cut down from the top to the top, and is triangulated with about 20 grams, cut side, disinfected side by side and dry. Drug impregnation or mixing followed by slices, with a significant effect on the united states high-tech product neb. Or if 40% of the ff is immersed in 200 times, then dry it in a cooling table within 0. 5 to 2 hours. You can't let the sun shine to the seed when you're dry. After drying up, they are sprung in layers on the earthbed, which is suitable for sandy soil, 80 grams of gold fungus and 100 grams of dt. Per cubic metre of soil, mixed with green with 1 or green with 10 grams of bacterizer no. 2, ready one day before the sprouts and wet enough to throw it out in groups. Slices are laid on one layer of a sprout bed, with wet soil of 1 cm thick, with a total of 3 to 5 floors covered in the upper layer and around the bed, with approximately 5 cm covered in the upper layer and around the bed, cutting blocks into bed for six to eight days, growing to 2 to 3 cm, removing slices and stacking them in the field with scattered light to make the sprouts greener。
Scrolling: spring potato cultivation is best done before the winter, before the spring sprouts flatten the land, before the planting is done, with 70 centimetres wide on the face, 30 centimetres wide and 15-20 centimetres deep in the ditch. Plantation: covered by membrane, suitable for 20-25 cm。
(b) base fertilizer: 667 m2 (one acre) of organic fertilisers in heavy fields, 5,000 kg, which is to be converted into the tillage layer in conjunction with deep tillage before winter. Fertilizers: fertilizers are applied as fertilizers in pre-plant ditches, typically 5 kg of urea or 10 kg of ammonium sulphate for 667 square metres, 15 kg of phosphorus fattening and 50 kg of grass-wood ash. Fertilizer recovery: based on the pattern of nitrogen-resisting potatoes and potassium elements, pre-maturized varieties such as large white balls and 25 flowers are best applied during seeding, typically 10 kg of urea per 667 m2 and calcium per phosphate. It would be preferable not to apply chlorine-containing potassium fat, with 0. 1 per cent of boron acid and 0. 02 per cent of copper sulphate sprayed during the flower period, with 50 to 70 kg per 667 square metres, with a five- to seven-day break and a good effect on the leaves of potatoes. The formulation is fertilized: in areas where potatoes are heavily grown, soil is taken to measure nutrients, followed by the application of recipes based on soil fertility and the demand pattern for potatoes。
Improved management diffusion of seedlings: 10-15 days after sowing, when the membrane is in place, the seedlings are extracted from the membranes and the holes are covered with soil. Watering: from a tree to a flower, the soil is not watered without drought. After flowering, the first three waters of the flowering period are key to the rapid expansion of the tubing, and the soil is always wet. Pre-literate varieties are found in three water-scarce sensitive periods, in the form of primary flowers, flowers and final flowering periods, and may result in significant reductions in production if there is insufficient moisture. Control the size of the chips in due course: the transition period from the seed to the potato is such that, if the potato is too strong, a 0. 1% dwarf or 50 - 100 mg/kg multi-active acetate solution can be sprayed, and when the multi-effect accelerator is sprayed, no drops can be made on the land. Take the buds in time。
The harvests of large white balls and 25-year-old varieties mature about 80 days after planting. The water must be stopped 7 to 10 days before the harvest, and the harvest should choose the clear weather to avoid damage to the chips as much as possible in order to facilitate storage. The membranes covered by the sowing are to be cleaned up after the harvest and buried or burned together。
Premium and late disease can be combated by 64 per cent of the venomicide humid powder 500 times more liquid or by the disease clean-up. The control of cyclic diseases is based on the choice of non-pathic, anti-pathological varieties, and on the sterilization of chips with agrococin or polycin. Soft scavengers can be combated by agro-chain carcinoxin, killing, dt, green one, green two, etc. The aphids are sprayed with aphids, reds, anti-aphids, silver gray membranes, and yellowboard booby traps。
