(1) cultivate strong seedlings. With seed propagation need to cultivate strong seedlings, with tender stem cuttings propagation only need to mow the stem insertion.
①Seed propagation. Cultivation of 1 month before sowing seedlings, early spring, winter seedlings in the protected area, the rest of the season in the open ground seedlings. Select fertile land, and appropriate application of fertilizer, made 1.5 m wide nursery beds, bed leveling, watering bottom water, and then sowing, generally 3 to 4 grams of seed per square meter, 15 m 2 seedlings for 667 m 2 land. Because the seeds are small, in order to make the sowing uniform, 50 grams of seeds first with half a basin of fine sandy soil mixed together with sowing, sowing covered with fine sandy soil about half a finger thick, and pay attention to keep the bed soil moist, in order to facilitate the germination and emergence of seedlings. After the emergence of seedlings, if you find insufficient fertility, can be appropriate to apply a small amount of fast-acting fertilizer, in order to promote strong seedlings, growth to 12 ~ 15 cm can be transplanted.
②Cuttings propagation. The use of bean curd stem nodes regeneration of adventitious root ability characteristics, intercepting its stem cuttings are easy to survive, the propagation of non-flowering fruit varieties is extremely convenient. Leave the seed mother stem in the winter can overwinter in the greenhouse, before planting as long as the mowing about 5 ~ 6 sections, 12 ~ 15 cm long strong young stem transplantation can be. Seedlings can even be planted in 2 to 3 sections when there is a shortage of seedlings, generally per 667 m 2 seedling field can be planted in 0.26 to 0.33 hectares of the field. If in the warm season, you can take stems directly from the production field transplantation, expanding the production area.
(2) land preparation, fertilization, border making. Cultivation of dryland bean curd, should be selected to facilitate drainage and irrigation of the plot, before planting combined with ploughing the land to apply adequate fertilizer, 23,000 to 4,000 kg per 667 meters, made 1.0 to 1.5 meters wide flat beds, leveling beds.
(3) Planting. According to different cultivation methods, after determining the planting time, select the seedling height of 12 ~ 15 cm of strong seedlings or intercepted tender, strong stems, planted into the soil 3 ~ 5 cm, 3 plants per hole, preferably semi-horizontal planting, plant spacing of 10 cm × 15 cm or 12 cm × 12 cm can be.
(4) Field management. Dryland cultivation, since the planting to keep the soil often moist, hot weather to avoid watering under the midday sun, to water in the morning and evening; in case of heavy rain but to timely drainage, to prevent drowning plants so as not to rot stems; protected cultivation of the main control of the growth of the temperature, and try to increase the light, to prevent damage. Regardless of dryland and paddy field cultivation, transplanting after the survival of the main fast-acting nitrogen fertilizer immediately fertilizer, and then every mowing 1 time, fertilizer 1 time, each 667 m 2 each time to chase urea 5.0 ~ 7.5 kg shall prevail, dryland planted fertilizer immediately after watering. Cool season fertilizer can also be used to rot human and animal feces and urine, each time per 667 m 2 1000 ~ 1500 kg. During the growth period, such as more weeds, should be pulled out in time.
(5) pest control. Diseases rarely occur in bean curd. Pests are mainly aphids, cabbage greenfly and small cabbage moths, which should be removed in time. Aphids can be used 10% of the imidacloprid (once a net) 1000 times solution for prevention and control, cabbage greenworms and cabbage moths can be manually captured or applied Ruijinte, chlorpyrifos and other insecticides for prevention and control; can also be used to kill the chlorpyrifos 1, 3, and Bt emulsions and other biopharmaceuticals such as spraying in addition to the treatment, the effect is good and no drug damage.
The growth process of the new stem and leaves of bean curd is the process of product formation, from planting to the beginning of the harvest in about 20 to 30 days, the young stem length of about 25 centimeters can be harvested mowed 1 time. Hand directly pull off or with a knife mow down the young stems, bundled into small handles, head cut off can be marketed, per 667 meters 2 per crop of about 1000 kg, and then every 10 to 20 days and can be mowed 1 time. Early spring or winter due to low temperature, slow growth, about 1 month can be mowed once. If the plant blooms in June, the plots that do not leave seeds can be mowed out of the upper part, leaving the middle and lower stolons to promote the sprouting of new stems, continue to produce and harvest.
