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.

Embodiment

[0033] The present invention discloses a composite pelletized grass seed production and processing technology and its application. In the present invention, four kinds of seeds have been tested, namely: Poa crymophila Keng and Festucasinensis keng. ), Elymus dahuricus Turcz and Poa pratensis Keng were all purchased from Huang Zhongtian Xing Grass Industry Co., Ltd. In the present invention, 4 kinds of pelletized materials are selected, which are marked as A1, B, R, and W respectively. Among them: A1 was presented by the Dutch Astec Seed Technology Company, the full name of the material is Astec A1; B and R are imported materials from Germany, the trade names are Bellerophpn and Rolexo respectively, and W is Jingyan Agronomics ( Beijing) Seed Industry Technology Co., Ltd. self-made material, the full name is JYYN-W, the company specializes in vegetable seed coating. The specific pelletization method is as follows:

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 particularly relates to a production and processing technology of composite pelletized grass seeds and its application. Background technique [0002] Grassland degradation is a serious and global problem. The restoration and reconstruction of degraded grassland has become one of the hot spots of domestic and foreign scholars' attention and research. Due to bad weather conditions and long-term irrational use, the alpine grassland on the Qinghai-Tibet Plateau in my country has been seriously degraded. The proliferation of rodents, insect pests and poisonous weeds derived from grassland degradation further aggravated the occurrence of degradation. Most of the degraded grassland has sparse vegetation and is dominated by poisonous weeds. Coupled with the constraints of natural environmental conditions, it is difficult to recover naturally, with slow results and long cycles. Therefore, it is neces...
