Cucurbitaceae seed shell processing method

Abstract

The invention discloses a cucurbitaceae seed shell processing method, belongs to the technical field of agriculture and relates to a shell processing method. The processing method includes the following steps: (1) the step of seed soaking, namely the step of soaking seeds in warm water with the temperature of 50-55 DEG C for 3-5 h, and soaking the seeds in cold water with the temperature of 20 DEGC for 5-7 h; (2) the step of caruncle removing, namely the step of selecting the middle horizontal line in two sunken parts formed by the two sides of caruncle and the ridge lines of the soaked seeds, and cutting off the upper parts of the caruncle from the middle of the two sunken parts along the horizontal line; (3) the step of accelerating germination, namely the step of performing accelerating germination on the seeds whose caruncle is removed at 25-28 DEG C, and performing sowing after the lengths of root buds reach 3-5 mm; (4) the step of seedbed disinfection, namely the step of performing spraying on the seedbeds per square meter with a disinfectant before sowing, and performing disinfection; and (5) the step of routine management, namely the step of performing sowing on the seeds,and performing covering management after sowing. The method can shorten emergence time, enhance emergence rates, eliminate rotten seeds and buds and reduce costs.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a method for treating seed husks, in particular to a method for treating the husks of Cucurbitaceae seeds. Background technique [0002] Cucurbitaceae crops include large seeds such as zucchini, watermelon, and squash. In the prior art cultivation of Cucurbitaceae crops, in order to increase the germination rate and shorten the emergence time, large-grain seeds of Cucurbitaceae including zucchini, watermelon, and pumpkin all adopt on-demand technology, and in order to ensure their emergence rate and emergence quality, it is necessary to break the During the seed dormancy period, on-demand sowing is carried out. The main point is to sow the selected high-quality seeds to the seedbed or hole tray after soaking and accelerating germination, and then cover the surface of the seeds with a layer of 1-2cm fabric. However, there are the following disadvantages during seed shell proces...

AI Technical Summary

Problems solved by technology

However, there are the following disadvantages during seed shell processing and on-demand sowing: 1) When breaking the seed dormancy period, the seeds are scratched, that is, the seed shell is scratched with a sharp object on the outer surface of the seed, and there is no standard for the depth of the scratch. It is difficult to grasp; the location of the scratch is uncertain; the number of scratches is different, and the scratch wound cannot be treated or protected; 2) Germination is slow, and the germination time takes about 5-7 days; 3) The germination rate is low, and the germination rate Generally 85-90%, the germination rate is lower under extreme weather conditions, and the weak seedlings produced are above 10-25%, which directly causes waste between 15-30%; 4) The phenomenon of rotten seeds and rotten buds is serious, And it is not easy to observe in a short period of time; 5) The emergence of seedlings is irregular, and there are many weak seedlings; 6) It is difficult to replenish cultivation when there is a lack of seedlings and broken ridges; 7) It is time-consuming and laborious, and the operation is cumbersome
