Land preparation. Choose loose and fertile fields and use manure as a base fertilizer. Stir evenly while tilling. Each column was planted at a distance of 1.2 meters, and the planting distance was 1313 cm. After planting, the bamboo piece was covered with an arched bracket, and the membrane was closed and heated to cultivate seedlings. Post-management. After 7 days of planting, when the film temperature is above 30 degrees Celsius, the film must be ventilated to prevent burning, and should be ventilated until late, and at other times to cover the film to promote chalky growth. Seedling stage topdressing. After 30 days of seedling age, the height of the seedlings was 20-25 cm, and colonization began. The temperature should not be too low. If it is too low, it should be postponed, otherwise it will affect the normal hair roots. It is best to use as much soil as possible to reduce mechanical damage to the roots. Combined with soil preparation, topdressing ammonium carbonate and calcium fertilizer. In the seedling stage, the vegetable stalk can also be sprayed to promote stem growth and increase nutrient transport. Control the water level. The water level of the colonized white seedlings was maintained at about 15-20 cm. After survival, a 10 cm water layer was maintained. After the pregnancy, the water is deepened to l6-23 cm, and after 1-2 harvests, the depth is increased to 30-35 cm, so that the entire whiteness sinks to the water. When the chalk reaches the peak of the tiller, the field should be filled into deep water to control the seedlings. Disclaimer: Some articles on this website are transferred from the Internet.
