Problems solved by technology

Paraquat is a contact herbicide, which is not safe for planting crops. Weeds around the planting holes need to be manually removed, which increases manpower and reduces weeding efficiency.
[0005] Weeding is a key step in crop cultivation. The selection of herbicides and the quality of herbicidal effect directly affect crop yield. There are no reports on safe and efficient weeding methods suitable for mixed planting of silage corn and forage sorghum, which seriously restricts the development of this technology.

Embodiment 1

[0062] The present embodiment provides a banded intercropping method and a mixed harvesting and mixed storage method of forage sorghum and silage corn, which are implemented in spring sowing fields in the Yellow River Diversion Irrigation District in Ningxia, and the specific operation steps are as follows:

[0063] (1) Land preparation

[0064] Last autumn, after harvesting the silage corn in late October, the field was ploughed, with a ploughing depth of 20cm; it was irrigated in winter on November 10, with an irrigation amount of 100m. 3 / mu; on February 3rd of the following year, mechanical soil moisture conservation was carried out; on April 11th, 5kg / mu of urea, 12kg / mu of diammonium phosphate, 5kg / mu of potassium chloride were applied, and the ground was rotated once with a depth of 15cm. Immediately pacify and protect moisture.

[0065] (2) Sowing

[0066] Mechanical sowing was carried out on April 15. The forage sorghum variety was F10, and the silage corn variety w...

Embodiment 2

[0087] The present embodiment provides a belt-shaped intercropping method and a mixed harvesting and mixed storage method of forage sorghum and silage corn, which are implemented in summer sowing fields in the Yellow River Diversion Irrigation District in Ningxia, and the specific operation steps are as follows:

[0088] (1) Land preparation

[0089] After the spring crops were harvested on May 20th, the water was irrigated to create moisture, and the surface of the field was flooded, and the irrigation amount was 80m 3 / mu; on May 29, 3kg / mu of urea, 13kg / mu of diammonium phosphate, and 4kg / mu of potassium chloride were applied, and the soil was rotated once to a depth of 20cm, and the soil moisture was immediately stabilized.

[0090] (2) Sowing

[0091] Mechanical sowing was carried out on May 30. The forage sorghum variety was Grand Prize 1230 and the silage corn variety was Jingke 968; the planting belt ratio was 1:1, and each belt was planted with 3 rows; The hole spac...

Embodiment 3

[0112] The present embodiment provides a strip intercropping method and a mixed harvesting and mixed storage method of forage sorghum and silage corn, which are implemented in the spring mulching field in the rainfed area of ​​southern Ningxia, and the specific implementation site is Jingyuan, Guyuan City, Ningxia Hui Autonomous Region. Haodian Village, Liupanshan Town, County, belongs to the hilly and gully area of ​​the Loess Plateau at the foot of Liupanshan Mountain, with a semi-humid climate in the middle temperate zone, with an average annual precipitation of 641.5mm. The specific operation steps of this method are as follows:

[0113] (1) Land preparation

[0114] On April 19, 25kg / mu of urea, 15kg / mu of diammonium phosphate, and 8kg / mu of potassium chloride were applied, and the soil was rotated once to a depth of 20cm, and the soil moisture was immediately stabilized.

[0115] (2) Ground herbicide closure

[0116] On April 20, the ground was sealed with 200 mL / mu of ...

Abstract

The invention provides a strip-shaped intercropping method and a mixed harvesting and storage method for feed sorghum and silage corn, and relates to the field of forage grass crop planting, harvesting and storage. A strip-shaped intercropping method for feed sorghum and silage corn comprises the steps of soil preparation, sowing and field management, 75% of sulfentrazone preparation, 48% of dicamba preparation and 25% of quinclorac preparation are compounded to serve as a special post-emergence herbicide for the feed sorghum and the silage corn, and weeding work is safe and efficient. The strip-shaped intercropping mode can effectively eliminate continuous cropping obstacles of silage corn single cropping, and has important significance for stabilizing forage grass supply in a region and improving the yield and quality of grass products. The mixed harvesting and storage method of the feed sorghum and the silage corn can realize mixed harvesting of the feed sorghum and the silage corn in the field, directly obtains a silage mixed raw material at one time, is convenient and rapid, is reasonable in proportion, can remarkably shorten an aerobic fermentation process after mixed harvesting and storage, enables the silage raw material to rapidly enter an anaerobic state, is beneficial to storage of nutrient substances, and improves the yield of the feed sorghum and the silage corn. The grass product quality is improved.

Description

technical field [0001] The invention relates to the field of forage crop planting, storage, and storage, in particular to a strip intercropping method of forage sorghum and silage corn and a mixed harvesting and mixed storage method. Background technique [0002] Forage production is the basis for the development of herbivorous animal husbandry. Affected by the ban on grazing on natural grasslands and the degradation of grassland productivity, artificial forage has become the main source of forage for livestock breeding. The supply capacity, product variety and product quality of artificial forage become the most critical factor in the development of herbivorous animal husbandry. C4 forage grasses represented by forage sorghum and silage corn have become the most popular in northern China because of their high light energy, water and nitrogen use efficiency and strong field resistance, and their dry matter yield is significantly higher than other forage crops. Regional sila...
