Early spring vegetable seedlings management points
In early spring, vegetable seedlings take a long time, grow slowly, and are vulnerable to adverse climate effects. Only through careful management can the goal of breeding strong seedlings to achieve high yields can be achieved. 1, cold insulation: According to the outside temperature level, timely cover (film or straw, etc.). Grasp the seedling temperature and temperature management. The temperature management must master the principle of “three highs and three lowsâ€: after sowing, it should be high before emergence and conducive to emergence and emergence of Qimiao; low after Qimiao, 9-10 at sunny hours, and ventilation at 2-3 pm; High, promote the growth of new roots, can not ventilate; live after the tree is low, nurturing strong seedlings, often ventilation; diarrhea seedlings after high, conducive to root extension; restore low growth, increase ventilation, prevent leggy, strengthen hardening seedlings. 2. Ventilation and light transmission: Ventilation and light transmission are the main measures for regulating the temperature, humidity, and air in the seedbed. After emergence, the shelters and ventilation work are done according to the climate and seedling conditions. Since the beginning of ventilation, it is necessary to maintain a certain amount of rainy days. Remove film, ventilation, light transmission time. 3, fertilizer and water management: the use of nutritious soil is generally not top-dressing, such as seedlings thin and thin, can be used natural organic nutrient solution 1000 times or give Baokang organic liquid fertilizer 500 times liquid foliar spray 1-2 times. 4, disease prevention and pest control: the seedling stage due to low temperature, weak light, more pests and diseases should be promptly prevented. Focus on the prevention of damping-off disease, blight and roots, and pay attention to the rotation of drugs and safe medication, shed should not be sprayed on cloudy days. 5, timely hardening seedlings: 7-10 days before planting, according to the changes in seedlings and the weather, gradually cooling, increase ventilation time, carry out hardening seedlings, seedlings to enhance resistance.
