Seedless watermelon bacterial fruit rot disinfectant and method for seedless watermelon free from shell breaking and accelerating germination

Abstract

The invention discloses a disinfectant for treating bacterial fruit rot of seedless watermelons and a shell-breaking-free accelerating bud-forcing method for seedless watermelons, wherein the disinfectant contains 2% Kasumin liquid 300-400 fold and 72% agricultural streptomycin sulphate 1000-1500 fold; and the bud-forcing method comprises: soaking seeds in water of 55 DEG C for 30min, then in the disinfectant for 3h, and in formaldehyde 100 fold for 30min after washed; flushing the seeds with saturated limewash until no mucus on seed surfaces, then flushing the seeds with clear water until no peculiar smell, and removing pericarp and wizened seeds; drying until the surfaces of the seeds turn white; wrapping the seeds with cotton cloth, placing the seeds into a thermotank, accelerating germination at 35 DEG C for 2h, and accelerating germination at 32 DEG C for 12-15h; washing the seeds with water of 35 DEG C, drying and dehydrating the seeds, airing the seeds until the surfaces have no obvious water, and waiting for germination in the thermotank of 32 DEG C. The disinfectant and the method can reduce probability for the seedless watermelons to infect bacterial fruit rot below 2 parts per thousand, have no need of artificial shell breaking, can reduce bud-forcing cost of the seedless watermelons, and raises a seedling rate of the seedless watermelon seeds.

Description

technical field [0001] The invention relates to the field of agricultural seedlings, in particular to a seedless watermelon bacterial fruit rot disinfectant and a method for preventing seedless watermelon from shell breaking and accelerating germination. Background technique [0002] Seedless watermelon has no seeds, good quality, convenient eating, high yield and disease resistance, and storage and transportation resistance. It is very popular among producers, operators and consumers. The planting area is gradually expanding, and it is cultivated all over the country. my country's seedless watermelon seed production bases are mainly in Xinjiang. Since 2007, domestic seedless watermelon seeds have been commonly infected with bacterial fruit rot, which has led to difficulties in the production of seedless watermelon seedlings. Some large-scale seedless watermelon production plants even The entire army was wiped out, resulting in no seedlings to grow in the field and serious ec...

Problems solved by technology

Therefore, the radicle of triploid seeds is not easy to drill out of the seed shell under natural conditions, resulting in a low germination rate of seedless watermelon seeds

In order to solve the problem of low germination rate of seedless watermelon seeds, the method commonly used by farmers and intensive seedling raising factories is to break the shell and accelerate germination. However, breaking the shell and accelerating germination requires a lot of manual work to break the shell, resulting in higher germination cost of seedless watermelon seeds. , and the cotyledon is easily damaged when the shell is broken, resulting in a low seedling rate
