Asparagus planting method and cultivation technology is what?

Asparagus is cold and drought resistant, chlorine and alkali resistant, suitable for growing in deep soil, high organic matter content, good permeability and water permeability, good drainage and irrigation conditions in sandy loam and loamy soil. The pH value of the soil is neutral, less than 5.5 or more than 8 acidic soil and heavy saline and alkaline land are not suitable for cultivation.

Normal growth of asparagus requires a variety of nutrients, in the large amount of elements to nitrogen, potassium, and less phosphorus, in the trace elements of calcium, zinc, manganese, chlorine is indispensable.

After cutting the dead stems in late autumn and early winter, the first to the grass fast to eliminate the growing perennial weeds; winter garden clearing after plowing and fertilizer, can be sprayed with chlorpheniramine, to prevent the occurrence of perennial weeds. Early spring before the young stem sprouting, in the cultivation of soil spraying herbicides to prevent the occurrence of annual weeds, which can be used fluroxypyr or Shi Tian supplement soil closure, anti-Matang, barnyard and other grass weeds.

Extended information

Sowing time for the use of the longest growing season, in the spring as early as possible. Sowing should take place when the ground temperature reaches 18°C to 20°C, after the frost period. The higher the ground temperature, even up to 32 ℃, the faster the germination. Sowing too late in the growing season can result in smaller mother plants. Therefore if sowing is too late in the growing season, use every method possible to encourage rapid, uninterrupted plant growth.

Seedling spacing and nursery bed construction A plant spacing of 5 to 7 centimeters results in better asparagus mother plants; too little spacing reduces the yield of the mother plant, and too much spacing wastes land. Seeds are sown in soil holes about 2 centimeters deep, which cannot be used if there are perennial weeds or land with too high a concentration of weeds each year. The finer the soil, the better it is for the cultivation of the mother asparagus plant, because it is easy to plow and transplant the mother plant.
