A production and processing technology of compound pelletized grass seed and its application

Abstract

The invention belongs to the technical field of agriculture and particularly relates to a compound pelletized grass seed production and processing process and application. Four grass seeds including Festuca Sinensis Keng cv. Qinghai, Poa Crymophila cv. Qinghai, Elymus dahuricus and Poa pratensisvat.anceps Gaud.cv. Qinghai are adopted as materials, and by experiments of seed selection, single-typeseed pelletizing, two-type seed compound pelletizing and the like, the compound pelletized grass seed production and processing process controllable in seed particle size and weight and ratios of different seeds is constructed and hopefully available for large-scale production and application. Compound pellets are obtained by processing of Festuca Sinensis Keng cv. Qinghai and Poa Crymophila cv. Qinghai, then compound pellets are obtained by processing of Elymus dahuricus and Poa pratensisvat.anceps Gaud.cv. Qinghai, and accordingly the two types of compound pelletized seeds can be close in size, weight and the like as far as possible. Therefore, in practical application, the two types of compound pelletized seeds can be mixed according to a certain ratio and used for grassland reseeding to guarantee a mixed seeding ratio of the four types of seeds.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a production and processing technology of compound pelletized grass seeds and its application. Background technique [0002] Grassland degradation is a serious and global problem, and the restoration and reconstruction of degraded grasslands has become one of the hot spots of domestic and foreign scholars' attention and research. Due to harsh climate conditions and long-term irrational use, the alpine grassland on the Qinghai-Tibet Plateau in my country has been seriously degraded. Rodent pests, insect pests, and poisonous weeds derived from grassland degradation further aggravated the degradation. Most of the vegetation in the degraded grassland is sparse and dominated by poisonous weeds. Coupled with the constraints of natural environmental conditions, natural restoration is difficult, slow and takes a long time. Therefore, it is necessary to curb grassland de...

Problems solved by technology

[0005] Supplementary sowing is an effective measure to restore alpine desertified grassland, but the implementation of supplementary sowing also faces certain technical problems: in degraded grasslands, the soil is barren and the water content is low. trampling and other reasons affect the germination and growth of supplementary grass seeds; the awns of artificially cultivated small forage grass seeds are easily damaged, and the seeds are not easy to germinate and grow in the soil; forage grass seeds have obvious differences in size. Not suitable for mechanized sowing

Seeds after pelleting have the defects of decreased germination rate and increased bacterial carrier rate, and this pellet processing method cannot achieve standardized and standardized production at present

In addition, there may be obvious differences in weight and size of different seeds, whether they are pellets or not. It is not easy to achieve uniform sowing in machine sowing or no-tillage sowing, and it is not easy to maintain the mixed sowing ratio of different types of seeds at the same level.
