Embodiment 1

[0014] (1) Selection of rootstock Choose pumpkin as the rootstock with strong grafting affinity, good symbiosis, resistance to watermelon root diseases, and strong stress resistance, and watermelon buds as the scion;

[0015] (2) Seedling preparation

[0016] The first is the plug, the choice of substrate, rootstock plug: length × width = 54cmX28cm 50-hole plug, scion plug: flat-bottomed seedling tray, length × width × height = 60cmx24cmx5cm, seedling substrate and ratio: substrate material, high quality Peat, vermiculite, waste mushroom material f or perlite 1, proportioning, the volume ratio of the three is 1:1:1, add 2kg of national standard compound fertilizer plus 0.2kg of carbendazim per cubic meter, and mix evenly as the substrate;

[0017] (3) Seedbed preparation

[0018] Sowing bed: The width of the seedbed is about 120cm, and the substrate is evenly spread on the seedbed with a thickness of about 8cm. Seven days before the seedlings are divided, the substrate is pre...

Abstract

The invention discloses a seedling raising method for watermelons. The method comprises the steps of rootstock preparation, seedling raising preparation, seedbed preparation, seedling raising, management in a sowing period, grafting and management of grafted seedlings. According to the method provided by the invention, watermelon grafting cultivation is performed on the continuous cropping ground,and above operation has the following advantages: 1, an occurrence of blight is effectively prevented; 2, the watermelons can be grown at lower temperature; and 3, a root system of pumpkin rootstockis stronger than that of a watermelon, the grafted seedlings have stronger water absorbing and fertilizer absorbing capacity, and the roots are widely distributed in soil, so that after the watermelons are grafted, fertilizers can be saved, and the yield of the watermelons can be improved; when tissue culture of triploid seedless watermelons is performed, root induction of vegetative propagation seedlings is more difficult, the vegetative propagation seedlings are used as scions to be grafted onto the pumpkin rootstock, so that a shortcoming that seedless watermelon seeds are difficult to reproduce is overcome; when industrialized seedling raising is performed, under the condition of small seeds, branches or buds are grafted onto the rootstock, so that a quantity of the grafted seedlings is greatly increased; and therefore, the method of using pumpkin and gourd as a rootstock and grafting watermelon seedlings is an effective way of development of watermelon planting.

Description

technical field [0001] The invention relates to a watermelon seedling raising method, belonging to the technical field of plant planting and seedling raising. Background technique [0002] Fusarium wilt of watermelon is a fungus that specifically attacks watermelon. The pathogen can survive in the soil for 7-10 years without a host, so watermelon cannot be continuously cropped. Watermelon seedlings must be grown by grafting in order to overcome the damage of watermelon blight to watermelon. Since the watermelon wilt pathogen does not infect the roots of gourds, pumpkins, and wax gourds, grafting watermelons with these rooted plants can effectively prevent the fusarium wilt from entering the watermelon plants, thereby avoiding the occurrence of fusarium wilt and solving the problem that watermelons cannot be continuously cropped , so that watermelon can be replanted. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the ...
