Abstract

The invention provides a seedling raising method for a watermelon grafting healing period. The seedling raising method comprises the steps of stock cultivation, scion cultivation, grafting, healing agent preparation and seedling raising management after grafting. According to the method, a centella asiatica extract and sodium alginate are adopted, the sodium alginate has good film-forming property and forms a thin film with a three-dimensional network structure after being cross-linked with Ca<2+>, and the specific surface area is increased, so that more centella asiatica extract is loaded on the sodium alginate, wound surfaces are protected, the drug effect is amplified, invasion of germs is reduced, wound healing is promoted, and the healing speed is accelerated; and under the catalytic action of Cu<2+>, free hydroxyl groups selectively break beta-1, 4 glucosidic bonds in sodium alginate to generate a large number of carboxyl groups, and the carboxyl groups have hydrophilicity, so that the water retention capacity is improved, nutrient substances are adsorbed, the slow release effect is improved, the withering phenomenon in the healing process is avoided, the grafting survival rate is up to 99%, a graft union can be healed within 50-68 h, the grafting cultivation time is shortened, and seedlings are healthy and strong and good in disease resistance.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for raising watermelon seedlings during the grafting and healing period. Background technique [0002] Watermelon is a common fruit that plays an important role in the agricultural economy. In the process of planting watermelons, pumpkin seedlings, gourd seedlings, etc. are generally used as rootstocks, and watermelon seedlings are used as scions. Disease resistance makes watermelon yield high and reduces the occurrence of disease phenomena. The quality of joint healing of watermelon grafted seedlings, the level of survival rate and whether it can exert the effect of disease resistance and increase production are not only related to the affinity of rootstock and fringe and the grafting method, but also affected by the grafting treatment and the environment and management after grafting. In the prior art , the plant healing agent is often applied around the interf...
