1. Select the site of disinfection Choose the land with high topography and good drainage for the seedbed. Add 200 grams of Bacillus cereus to the nutritious soil of each side to disinfect the soil.
2, to prevent the emergence of seedlings When the emergence of uneven seedlings or no signs of emergence, should check the seeds in the seedbed, if the seed radicle yellow tip rot, indicating that the seeds can not normally germinate, should carefully find the reasons to improve the seedbed environmental conditions, and Immediately reseeding; if the tip of the radicle is still white, it means that it can germinate normally. The management of temperature and humidity should be strengthened to promote seed germination; when large and small seedlings appear, the large seedlings can be moved to a lower temperature on the greenhouse front to make the seedlings grow stronger. Neatly consistent.
3, to prevent the roots of the roots once roots, timely ventilation and humidity, increase evaporation, ground cultivation, loose soil, increase permeability; such as the soil is too wet, can be sprinkled with some fine dry soil or coal ash, so that bed soil temperature as soon as possible Increased. Multilayer covering is used to facilitate heat preservation and ground temperature rise, and temporary warming is performed at low temperature or in continuous shade, rain and snow days.
4, nurture strong seedlings to adjust the temperature, humidity, light of nursery bed, is conducive to the cultivation of strong seedlings. 1 In case of overcast yin, rain and snow days, it is also necessary to pay attention to removing the opaque covering to make the seedlings look light. 2 The temperature difference between day and night can be gradually increased with the growth of the seedlings, and the night temperature is appropriately lowered. The night temperature after emergence is not higher than 18 °C, but also to properly control the amount of watering and nitrogen fertilizer application, spraying 0.3% of potassium dihydrogen phosphate or Jian Bo 500 times liquid; 3 timely sub-seedling, seedling density when the seedlings generally require 10 cm square, If seedlings are fed with nutrients, seedlings can be thinned according to seedling growth.
5, to prevent flash seedlings ventilation should be open from the lee side, vents from small to large, time from short to long. Rainy weather, especially on cloudy days, should be properly exposed to allow the seedlings to see the light.
6, to prevent injury 1 correct use of pesticide species, use chaos, with the use of appropriate concentration and frequency; 2 medication, depends on the day, see the land, see the seedlings, to avoid adverse weather, bad public opinion, not Strong seedlings, the application of high quality, spraying evenly and moderately; 3 after the emergence of phytotoxicity, in a timely manner with "Health and Planting Po + Wan Shuai No. 1" or "Huiguang alginic acid" spraying seedlings to ease the injury.
