It is best to use high quality, good quality imported seeds for good varieties, and domestically produced hybrids. Seeds are full and mature. The new seeds are best sowed after a period of dormancy. Before sowing, the seeds are dried for 2-3 days and then disinfected. For each kilogram of seed, use 50% carbendazim WP 5g or 70% thiophanate-methyl 5g, add 125 kg of water and soak for 24 hours. After sterilizing, immerse it in warm water at 30°C for 2-3 days. After the seeds have enough water, remove and drain, and germinate at 25-30°C. The seed surface is covered with a moist cloth. 10% -5% of the seeds germinate when exposed to white.
80% of loose and fertile soil (screened) and 20% of decomposed rot fertilizer are used to prepare sowing and sowing, or 50% of pond mud, 3% of fine river sand, 15% of grass ash, 15% of compound fertilizer, 0.5% of urea, and superphosphate 1% calcium, potassium chloride 2% prepared nutrient soil, add the right amount of water, hand into a group, landing that degree of dispersion. The nutrition bag is 12 cm high, 7-10 cm in diameter, and 1-2 holes at the bottom. The nutrition soil is installed about 1 cm from the bag mouth. Choose flattened, sunny, water and irrigation convenient place to place nutrition bags, each nutrition bag on demand 1-2 seeds, pull a cover of a thin layer of nutrient soil, cover the straw, drench water to make nutritious soil and straw wet. Green reed autumn broadcast suitable period in October-November.
Seed management during seed germination, daytime bed temperature is controlled at 25-30 degrees, keeping the nutrient soil moist. Wait for 50% of the seeds to emerge and gradually remove the straw. Seedling growth period seedbeds maintain 20-25 degrees during the day and keep 15-18 degrees at night. When the seedling height is 10 centimeters, per acre, it will be poured with 300-400 kg of 0.6% urea solution. After every 15-20 days, it will be applied once. Every time, 50 kg of human excreta will be added with 250 kg of water. After the second layer of seedlings was removed from the ground, the concentration of fertilization was appropriately increased.
Timely transplanting seedling height 40 cm, 0.5 cm high when transplanted. Small arch cover. When planting transplants, the plants that are robust, non-invasive, and free of pests and diseases should be selected, and male plants should be planted as far as possible. After being properly transplanted, the bamboo shoots can be harvested after 8-10 months, 200-300 kilograms per year in the second year, and 500 kilograms per year in the third year. The fourth year will enter into a period of rich production with 800-1000 kilograms per mu. Continuous harvesting bamboo shoots for 10 years.
Seeding green asparagus in autumn, nutrition bag nursery, with the advantages of rapid emergence, high nursery rate, labor saving, early production and so on.
