Abstract
Aiming at the problems of high temperature and drought in Xinjiang Turpan area and low survival rate of melon seedlings transplanted in dry land, the existing transplanting machine is the key to mechanized and non-destructive transportation and planting of large plants of young tender melon seedlings, root water injection, and precise soil piling in planting holes. Technical difficulties, the design of a double melon planting machine for laying pipes and membranes, watering and transplanting, can complete rotary tillage, spreading drip irrigation belts, laying mulch and covering the soil around the membrane, transplanting pot seedlings on the membrane, and water injection at the bottom. This machine puts the water injection pipeline under the inner side of the transplanter, and through the multi-point linkage electric control, the seedling preservation water is injected into the bottom of the seedlings pot while the seedlings are transferred, which not only ensures the survival rate of the melon seedlings, but also an accurate piling of the planting hole is realized. The technology of transplanting with water and piled soil for planting holes effectively solved the technical problems of mechanized transplanting of cantaloupe under high temperature and arid climate conditions in Turpan. The survival rate of melon seedlings under drip irrigation for 8 hours after transplanting in dry land exceeded 97%. The efficiency of mechanized operation can reach 0.07 ha/person/hour, which is more than 8 times higher than manual operation. The operation speed of the machine is 1~1.2m/s, and the transplanting quality rate is 93.26%, meeting the requirements of cantaloupe transplanting agronomy.
