Embodiment 1

[0024] 1. Selection of forest land: select a forest land with a canopy density of 40%;

[0025] 2. Sowing of alfalfa and chicory: (1) according to the light transmittance of different positions in the woodland, divide the plots with 30-100% light transmittance and 0-29% light transmittance; 100% light transmittance plot, mixed sowing by alfalfa and chicory 60%: 40% weight ratio, the sowing rate is 2.0kg / mu; do not sow in the plot of 0-30% light transmittance, as the end of grazing The rear chicken's habitat and activity site form a kind of understory chicken grassland that improves chicken immunity and reduces chicken total cholesterol content; (3) when the alfalfa and chicory average height of the sown grassland reached 15cm, the grassland was used for grazing.

[0026] 3. Grazing 30-day-old chickens on grassland, the immune organ index (spleen) and lymphocyte transformation rate of chickens in the 60-day-old period were improved by 43.2% and 29% respectively than those of th...

Abstract

The invention provides a planting method of underwood grassland for breeding chickens, which pertains to the agricultural technical field. The method comprises the following steps: firstly, a forest land with a canopy density less than 70 percent is selected; secondly, purple alfalfa and chicory are sowed in a mixed way according to a percentage by seed weight of 30 to 60 percent and 70 to 40 percent, namely, each kilogram of mixed sowing seeds contains 0.3 to 0.6kg of purple alfalfa seeds and 0.7 to 0.4kg of chicory seeds, the sowing rate is 1.5 to 3.0 kg / mu (mu: a Chinese unit of area, 1 / 15 of a hectare), thereby forming an underwood grassland for breeding chickens, which can improve the immunizing ability of the chickens but reduce the total cholesterol content in the chickens. Breeding and utilizing the grassland start when the purple alfalfa and the chicory planted on the grassland grow to an average height of 15cm. The underwood grassland of the invention is characterized by improving the immunizing ability of the chickens, reducing the total cholesterol content of the chickens, saving feed, promoting the economic benefit of ecological forests and economic forests and producing high quality chickens.

Description

technical field [0001] The invention relates to a grassland planting technology in the field of agricultural technology, in particular to a method for planting grasslands for chickens under forests. Background technique [0002] Alfalfa (Medicago sativa L. hereinafter referred to as alfalfa) is a perennial leguminous plant with rich nutritional value. Alfalfa has three major functions of nutrition, health care and physiological regulation, and has special effects in increasing the weight of livestock and poultry, enhancing the immunity of livestock and poultry, and reducing animal cholesterol. [0003] Chicory (Cichorium intybus L.) is a perennial herbaceous plant of the genus Cichorium in the Asteraceae family. It is a high-quality feed for livestock and poultry, and has the function of reducing serum cholesterol (TC) and triglyceride (TG). [0004] Found through literature search to prior art, Zhao Kun et al. (2005) reported using alfalfa polysaccharide as the enhancer of...
