Autumn fresh green asparagus fresh shoots put into production early

Green asparagus is a medicinal and food-use economic crop, its tender stems are tender and delicious, and have high nutritional value. It is one of the ten most famous dishes in the world. The cultivation of green asparagus in autumn can be used to raise seedlings in a nutrition bag. This method has the advantages of rapid emergence, high nursery rate, and labor saving. The technical points are introduced as follows for reference by farmers. 1. When choosing green asparagus, the varieties should be the first choice for high-yield, high-quality imported varieties, followed by domestically-selected hybrids. Seeds are sown before sowing. Seeds with full grain and high maturity are selected. The sowing date is from October to November. 2. Before the seeds were sown and sowed, the seeds were left to dry for 2-3 days in sunny days, and then the seeds were disinfected. There are two methods of disinfection, one is to use 50% carbendazim WP or 70% thiophanate-methyl 50g, 12.5 kg of water, fully dissolved and then put 10 kg of seeds, soak for 24 hours after the removal; Use 5% sodium hypochlorite 1 part, add 4 parts of fresh water, stir well and put it into the seed, soak it for 2 minutes, then remove it and rinse it with cold water for 1 minute. After the seeds are sterilized, they are soaked in warm water at 30°C for 2-3 days. After the seeds are fully swollen, they are removed, drained, and then placed in an environment of 25°C to 30°C for germination. When germinating, the surface of the seed is covered with a layer of wet cloth or wet burlap to maintain the moisture of the seed. When the umbilical portion of the seed is exposed to 10%-15%, it can be sown. 3. When making nutritious soil by bagging and sowing, the soil can be taken out from loose and fertile plots. After sieving, 2 parts of decomposed circumfertilizer are mixed for every 8 parts of soil, and 50% of pond mud, 30% of fine river sand, and 15% can also be used. Plant ash, 1.5% compound fertilizer, 0.5% urea, 1% phosphate fertilizer, 2% potassium chloride mixed preparation. It is advisable to add appropriate amount of water to the nutritious soil in order to make it into a group by hand. The nutritional bag is 12 cm high, 7-10 cm in diameter, and 1 or 2 holes at the bottom. The nutrition soil can be installed about 1 cm away from the bag mouth. Choose nutritional bags in flat, sunny places. Each nutrient bag must have 1-2 seeds sown and a thin layer of nutrient soil. Then cover the rice straw with water and apply water and nutritious soil and straw. 4. Seedling Management Green asparagus can be planted in about 30 days after sowing. During the germination of the seeds, the temperature in the pans is controlled between 25°C and 30°C during the day, and the nutrient soils are often kept moist. When 50% of the seeds have emerged, gradually remove the straw. The temperature during the growth of seedlings is preferably 20°C to 25°C during the day and 15°C to 18°C ​​during the night. When the seedling grows to 10 cm in height, the urea solution is added in an amount of 300-400 kg per mu and every 15-20 Once on top of the fertilizer, each application of diluted human excrement (50 kg of human waste water 250 kg), when the second ground stems after the withdrawal, the fertilization concentration should be increased. Seedlings are more sensitive to temperature, light, and moisture. During their growth, they should keep the nutrient soil moist and not be over-stressed or over-arrested. When the seedling height is 40 cm or more and the stem diameter is 0.5 cm, it can be transplanted to Daejeon and a small arch shed can be erected. After the temperature rises, the arch shed is removed. When transplanting, attention should be paid to selecting seedlings that are robust, non-damaged and free of pests and diseases. In the land where the water and fertilizer conditions are better, the plants can be harvested after 8-10 months of growth, and the yield is lower. The second year can produce 200-300 kilograms of fresh bamboo shoots, and the third year can produce 500 kilograms of fresh bamboo shoots. Around the 4th year, the 4th year is a period of asparagus production, with a yield of 800-1000 kilograms per mu. Green asparagus is a medicinal and food-use economic crop.
