Bean and potato, also called edible gems, can produce 1,500 kilograms of vine leaves per acre, containing 23% of crude protein, and is a high-quality forage; at the same time 2800 kilograms of tubers per acre, 40% of flour production, starch is rich in protein, amino acids, and more The vitamins and trace elements can be made into powder, fans, noodles, cakes, and tastes fresh. It can also treat coronary heart disease, angina, diabetes, etc. It is a rare green food that combines nutrition and diet.
I. Breeding of seedlings
In the summer, the potato pieces are transplanted to the nursery, and after germination and emergence, the soil is embedded in the vine leaf stem segments to form new plants. In November, the plants were excavated, and the vines were cut in a length of 17-30 cm. Then, each 5-10 plants were cut into bundles, soaked in 200-fold Bordeaux mixture, discharged into the pits, covered with fine sand, and covered. Temperature control above 0 °C, ready for wintering.
Second, the cultivation method
1. Positioning digging piers and germination: After the vernal equinox is the appropriate period for transplanting seedlings. First inoculate seedling size, determine the number of plants per acre, general seedlings per acre planted 300-360 strains, seedlings planted 600-700 strains, seedlings planted 1200-1400 strains. Divided by 1.331.66 meters row spacing, pit depth 33 cm, and then applied human waste, 200 kg per mu, calcium magnesium phosphate fertilizer 15 kg. The germination should be early. 30 days before the seedlings are transplanted, the plastic film shall be covered on the seedling pits to encourage the seedlings to shoot and then transplant.
2. Transplanting Seedlings: Seedlings should be coated with bone powder (1.5 kg per mu) during transplanting, and then be planted in the pit at approximately 15 degrees. After planting, put bricks 2-4 around the seedlings.
Third, management
1. Weeding: Weeding in time.
2. Fertilization: There are rhizobium-fixing nitrogen in soybeans. In addition to basic fertilizer, generally 15 kg of superphosphate, 6 kg of ammonia bicarbonate, 2 kg of urea, 50 kg of vegetation ash, and 10 cm deep under the soil 20-30 cm Topdressing can also be used to fertilize foliar fertilizers.
IV. Pest control
Insect pests are pod borer, worm borer, leaf roller borer, and polyphagous sturgeon, etc. Control can be used to dip 1500 times dimethoate or dichlorvos 1000 letter liquid spray. From July to August, 100 grams of dimethoate can be added to the base of the water 2000 times. In the case of bacterial diseases, 100 times Bordeaux mixture or 500 can be used to administer the rice indica, and it is also possible to use lime granules mixed with ash.
