1. Planting time: Asparagus is usually planted in April-May in spring. If it is planted in a greenhouse, it can also be planted in August-September. The tender stems can be harvested in the following spring, and the output in previous years is higher year by year. Planting for 4- 10 years is the high yield period. Asparagus should be planted in places with high terrain and convenient drainage. Radish and vegetables should not be planted on the land before farming.
2. Planting method: put the seeds into 400 times solution of 50% carbendazim or 70% kitobuzin, keep the water temperature at 25-30%, disinfect for 24 hours, then rinse with clean water, and soak the seeds in warm water at about 30℃ for 2-3 days. After the seeds fully absorb water, wrap them in gauze or towel and put them in an incubator or a warm place to accelerate germination. In the meantime, water should be sprayed or washed frequently, and sowing can be done after 2-3 days. The amount of seeds used for sowing is about 10kg per mu, and the amount of seeds used for on-demand sowing and drilling is about 1kg per mu, and the seedlings begin to emerge 15-20 days after sowing.
Matters needing attention in asparagus planting
Top dressing can be applied one month after planting, mainly with fecal water, and the concentration can be appropriately increased once in the next two months. Loosening and weeding in intertillage soil, combining shallow intertillage soil 1-2 times to prevent root system from being exposed. The tender stems planted in that year should be kept. After 80% of the seeds are unearthed, the plastic film can be removed one after another. Pay attention to washing water lightly, weeding and topdressing, and prevent and control underground pests in time when they are found.
Topdressing should start one month after planting, with diluted cake fertilizer water, organic fertilizer solution and manure water as the main materials. After autumn, the concentration of fertilizer can be gradually increased, and water can be poured once every half month and once every 65,438+00 days in summer. When harvesting in spring, the soil should be kept moist. After four years of planting, three-element balanced ternary compound fertilizer should be applied every autumn and winter.
