1. Avoid low temperature when transplanting After the transplanting, the temperature of the watermelon should be about 15 degrees. In the early spring, the melon seedlings transplanted often encounter the ground temperature of 10 centimeters less than 15 degrees and can not be rooted, resulting in dead seedlings or seedlings not long. Treatment plan: transplanting should be carried out after raising the ground temperature by using the method of laying the membrane in advance, and the survival rate can be reduced to reduce the death of the melon seedlings. 2. Avoid using fertiliser and organic fertilizer as base fertilizer. After transplanting the watermelon, if the roots directly contact the fertilizer or there is no organic fertilizer that is decomposed, it will easily produce roots and cause dead seedlings. Treatment plan: Firstly, the base fertilizer must be fully blended with the soil to avoid excessive root fertilizer concentration. The best one is to use it together with microbial bacteria. Through the transformation of microbial bacteria, the use of fertilizers and organic fertilizers can be increased, and the fertilizer can be reduced. phenomenon. 3. Avoid transplanting seedlings Treatment plan: The best time for watermelon transplanting is watermelon four-leaf stage. Seedlings because of small growth, poor adaptability and resistance to the outside world, slow seedlings slow, susceptible to disease invasion, and even death of seedlings. Transplanting more than five leaf stage, because the root has been formed, it is easy to hurt the root system when transplanting. 4. Avoid seedbed dry Treatment plan: Before transplanting, the seedbed should control the temperature without controlling the water. When transplanting, if the soil is too dry, it is easy to disperse and injure the root system. After transplanting, under the condition of maintaining the ground temperature, the water bed should be pressed carefully. 5. Avoid ignoring soil management before transplanting There are many pests and germs in the soil. With the increase of the ground temperature, the occurrence period of pests and diseases will be relatively early. The best solution before transplanting is to use the microbial inoculant and transplant it 10 days later. It is also possible to apply the microbial inoculants after watering after transplanting. The action of the microbial inoculants is to eliminate the soil. Viruses in the bacteria reduce the incidence of damping-off, stem rot, eliminate soil acidification and provide a good environment for root growth. 6. Avoid early dressing and watering Treatment program: watermelon in the raising of the top dressing, that is, watermelon seedlings after the five-leaf period, the use of fertilizer should be based on the growth of melon seedlings and soil fertilizer to determine the amount of fertilizer, NPK fertilizer can be applied after the watermelon transplant. Premature fertilization supplies are harmful. Anesthesia Medical Co., Ltd. , https://www.jssinoanesthesias.com
