Method for threshing mitsuba seeds

Abstract

The invention relates to a method for threshing mitsuba seeds. The method comprises the following steps: firstly, after the mitsuba seeds are matured, when dew is not dry on a sunning morning, harvesting aerial stems and leaves, placing outside for 7-10 days for maturation, and during the period of seed after mature, spraying abscisic acid aqueous solution for treatment for one to two times on the stems and leaves; secondly, drying the mitsuba after maturation in the sun, and beating the mitsuba stems and leaves after being dried for threshing; and thirdly, air-separting the seeds after threshing, and sieving so as to achieve the purposes of completely separating the seeds from the stems and leaves and obtaining the seeds with better quality. The method is simple and convenient to operate, the yield of the seeds can be achieved to 61.7 kg / mu, the germination rate can achieve 94.2%, the volume weight can achieve 497.2 g / L, and straws are manually beaten after maturation treatment for threshing, so that matured seeds can be easily beaten down, and unmatured seeds mostly remain on the straws; and therefore, the seed yield is improved, and the seed consumption during the threshing process is also prevented.

Description

technical field [0001] The invention relates to a method for threshing plant seeds, in particular to a method for threshing celery seeds, and belongs to the technical field of agriculture and forestry. Background technique [0002] Clover celery (Cryptotaenia japonica Hassk.), also known as duck celery, mountain celery, wild Shu celery, etc., is a perennial herbaceous perennial plant of Umbelliferae and japonica Hassk. The whole plant can be used as medicine, and the tender stems can be eaten as vegetables. Every 100g edible part contains 1.1g of protein, 2.6g of sugar, VA100 international unit, VB10.04mg, VB20.02mg, calcium 44mg, phosphorus 38mg, iron 0.8g, so clover is very popular in the international market, Japan In countries such as South Korea and South Korea, the cultivation of celery is mainly through hydroponics, and the demand for seeds is very large. A large amount of celery seeds need to be imported from my country every year. Germination rate and bulk density a...

Problems solved by technology

Since the seeds on the celery mature one after another, the maturity time of the seeds on the same plant is inconsistent. When the stems and leaves of the celery are repeatedly patted with a connecting rod after harvest, it is difficult to grasp the force, especially most people use force to increase the seed yield. Larger, this will cause many low-maturity seeds to fall off together with the awn, which not only brings difficulties to the later seed selection, but also causes the overall quality of the seeds to be low, and the proportion of seeds with poor quality in the harvested seeds At this time, winnowing and screening methods are usually used to improve the overall quality of seeds and remove unqualified seeds. Because the seeds are long and spindle-shaped, if the quality of seeds is to be greatly improved, winnowing and screening are the most important way to remove unqualified seeds. At the same time, more qualified seeds will be removed, and the loss of seeds will be greater, which will affect the economic benefits

At present, there is no easy and economical method to improve the germination rate and bulk density of celery seeds
