Method for grafting watermelon by utilizing millstone pumpkin as stock

Abstract

The invention discloses a method for grafting watermelon by utilizing a millstone pumpkin as a stock, which comprises the steps of seed selecting and disinfecting, firstly soaking seeds (millstone pumpkin seeds and watermelon seeds) into a well-prepared water tank filled with two parts of boiled water and one part of cool water, wherein the water temperature after mixing is 60-70 DEG C and the water quantity is five times than the seed quantity; then fully stirring, rinsing the seeds with clean water after the temperature is lowered down to 37 DEG C, later soaking the rinsed seeds in the cleanwater for 11-12 hours, fishing out and putting the seeds in a constant temperature cabinet for accelerating germination; subsequently earthing up, sowing and grafting, wherein the grafting can be implemented by using a peg graft method, an approach grafting method and a cleft grafting method; after grafting, sprinkling water mist on the second day, photosynthesizing and permanent planting after 20-25 days. The watermelon grafting method is characterized by reducing blight, improving output and controlling survival rate to be over 95 percent.

Description

technical field [0001] The invention relates to a grafting method for grafting watermelons, mainly using local mopan pumpkins as rootstocks for grafting watermelons. Background technique [0002] Watermelon grafting cultivation is an effective measure to prevent diseases and insect pests, increase yield, and is easy to operate. Using the disease resistance and huge root system of rootstocks, the survival rate of watermelon continuous cropping fields can be controlled above 93%. There are many methods of watermelon grafting, such as plugging, docking, sticking, splitting, etc. The plugging method is relatively simple, has a high survival rate, and is widely used. In the mountainous area of ​​southern Anhui, most of them use mopan pumpkins as rootstocks. In the process of grafting, improper use methods cause defects such as watermelon wilt and low yield, and the survival rate is only about 80%. Contents of the invention [0003] The purpose of the present invention is to ov...
