Sherry red can be sown in spring, winter and fall, winter and spring type is usually planted in late September, fall type in late July.
Sherry red planting methods:
1, land preparation, before sowing the land for deep turning, the bottom of the fertilizer, per acre of fertilizer can be rotted organic fertilizer 500 ~ 1000 kg, and then make the bed, the width of the bed is 150 cm or so, in the bed sprayed with 50% of the 1000 times the solution of Phosphorothioate to prevent underground pests.
2, sowing seedlings, the seeds with 10% trisodium phosphate soaked or mixed with zinc and other pesticides. Sowing is available in the way of spreading evenly on the bed, and then covered with a thin layer of fine soil. After the emergence of seedlings in a timely manner between seedlings, seedling spacing is maintained at 2 ~ 3 cm, after the inter-seedling application of a nitrogen fertilizer and water to promote seedling growth. Do a good job of pest control during the seedling period, thus reducing the infection of virus disease.
3, planting, when the age of the seedlings to about 30 days, seedlings grow to 5 ~ 6 true leaves when planting, planting density for the row spacing 30 ~ 40 cm, plant spacing 25 ~ 30 cm, planting the roots of seedlings with soil, to prevent root damage, planting after watering the roots of the full water, each mu of land can be planted about 5500 seedlings.
Extended information:
< p>Sherry red after the termination of the management and control:
1, field management, about 15 days after planting plowing, weeding, to prevent the soil from knotting, so that the soil permeability to promote plant growth, according to the growth of the situation of the arrangement of the 2 ~ 3 times plowing.
2, fertilizer management, seedling survival after fertilization, fertilizer mainly nitrogen-based fertilizer, while the appropriate application of phosphorus and potassium fertilizer to improve disease resistance and improve yield. Generally in the plant's entire growing period total **** three fertilizer, transplanting a light fertilizer water, mid-December with ammonium carbon and phosphate fertilizer 20 kg each, mid-February with 20 kg of urea, 15 kg of potash fertilizer after a.
3, the control of pests and diseases, snow red pests and diseases are mainly virus disease and aphids, control methods, virus disease can be used in the early stages of the disease 20% virus A wettable powder 500 times liquid or 2% of the bacterial grams of poisonous grams of water 250 times liquid, etc., and at the same time, combined with the use of growth promoters. Aphids can be controlled with pesticides such as 10% once again net wettable powder 1500 times solution.
