Problems solved by technology

Stylo is a warm-season perennial pasture. The growing season is generally from June to early October. It can grow for 4 years after transplanting in the first year. The growth of Stylo after October is small. For perennial crops , need to wait until June of the second year to re-germinate and enter the vegetative growth p

Embodiment 1

[0035] (1) Reasonable dense planting

[0036] In the arable land in the dry and hot valley of the Jinsha River, combined with land preparation, apply 7500kg / hm of decomposed farmyard manure to the entire planting land 2 and superphosphate 400kg / hm 2 , dig a planting pond, and the distance between the rows of stylotypes during planting is 40cm×55cm; during the rainy season in the dry hot valley of the Jinsha River, transplant the stylotype seedlings into the planting ponds, and plant 1 to 2 plants in each pond.

[0037] (2) Field management of Stylophyllum

[0038] ① Topdressing management: In the first year after transplanting and surviving Stylophyllum seedlings, when the new leaves germinate, apply urea with an N content of 46% mass fraction once in each Stylophyllum planting pond ring, and the urea dosage for each ring application It is 0.003kg per pond, and the interval between two ring application of urea is 15 days;

[0039] ② Timely drainage and irrigation: During th...

Abstract

The present invention discloses a cultivation method for interplanting stylosanthes guianensis and annual ryegrass, and belongs to the technical field of herbage production. The method comprises the steps of rational close planting, stylosanthes guianensis field management, stylosanthes guianensis mowing utilization, ryegrass interplanting, ryegrass field management, ryegrass mowing utilization and ryegrass multiple cropping. According to the method, after decomposed farm manure and calcium superphosphate are applied to arable land of Jinsha River dry-hot valley, field planting ponds are dug to plant the stylosanthes guianensis; the stylosanthes guianensis field management comprises the steps of topdressing, draining flooded fields and irrigating, weeding and controlling insect diseases; and topdressing the stylosanthes guianensis after every mowing, and interplanting ryegrass seeds from the end of September to October after mowing the stylosanthes guianensis in the first year. According to the method, the defect of greenfeed shortages in the autumn and winter of the Jinsha River dry-hot valley is overcome, a new raw material production method is provided for development of winter animal husbandry of the Jinsha River dry-hot valley, waste of water resources, production cost and land resources is reduced, and compared with a method of only planting the stylosanthes guianensis, the benefit per mu can be increased by 338-959 yuan.

Description

technical field [0001] The invention relates to a cultivation method for interplanting stylo grass and one-year ryegrass, belonging to the technical field of forage grass production. Background technique [0002] Stylosanthes spp. has the characteristics of nitrogen fixation, fast growth, cutting resistance, applicability, and strong drought tolerance. It has good palatability and is an important leguminous forage and forage plant in tropical and subtropical regions that cattle, sheep and other livestock and poultry like to eat. Annual ryegrass (Lolium multiflorum Lam.) likes a warm and humid climate. It grows faster than other grasses in autumn and spring. It is rich in nutrients, high in quality, and good in palatability. All kinds of livestock like to eat it. Stems and leaves contain 13.7% protein, 3.8% crude fat, and 21.3% crude fiber in dry matter. The grass is good in quality and suitable for green feeding, hay preparation, silage and grazing. It is suitable for raisi...
