Monocotyledon approach grafting method

Abstract

The invention discloses a monocotyledon approach grafting method, which comprises the following steps of: (1) proper grafting period selection, wherein bottle gourd rootstock seeds are sown and cultivated 6 to 8 days in advance and then watermelon scion seeds are sown, and the proper grafting period is the period when the rootstocks and watermelon grafting plants are basically in the same size, namely when watermelon cotyledons expand and the first euphylla of the scion plants grow; (2) rootstock treatment, wherein rootstock growing points are removed by bamboo plates, the part close to the cotyledon side is cut downward at an angle of 75 degrees by a blade, one cotyledon of the rootstock is cut, the cut depth is 20 percent based on the diameter of the hypocotyl and the length is 0.7 centimeter; (3) scion preparation, wherein the part, 0.5 centimeter away from the cotyledon, of the upper end of the watermelon grafting hypocotyl is cut at an angle of 25 degrees and the cut length is 0.7 centimeter; (4) approach grafting, wherein the cuts of the rootstock and the scion are adhered and aligned, the cuts are clamped by a grafting clamp and the grafted product is placed in a seedling re-growing chamber to allow the cuts heal and re-grow after the grafting is completed. The monocotyledon approach grafting method has the advantages of high survival rate, high working efficiency and the like and is also suitable for grafting varieties, such as bitter gourds, with a low grafting survival rate.

Description

technical field [0001] The invention relates to a grafting method, mainly a monocotyledon grafting method. Background technique [0002] Grafting method conventionally has inserting method, cleaving method, has following deficiency: grafting affinity is poor, survival rate is low, and grafted seedling growth vigor and adaptability are weak, and growth rate is slow, and output is low; When the rootstock and scion are disproportionate due to the end of the top insertion period or other reasons, the operation is complicated and the work efficiency is greatly improved compared with the conventional docking method. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the present invention provides a monocotyledon grafting method, which has the advantages of high survival rate and high work efficiency, and is also suitable for varieties with low grafting survival rate such as bitter melon. [0004] The present invention solves the technica...
