通过对桐乡青、新一之濑两个桑品种10种不同栽植形式,9种不同栽植密度桑的饲料效率研究,结果表明:食下量、消化量、消化率、全茧量、茧层量74%的试验区不高于5%;茧层、茧重转化率和生产效率未达到显著水平.说明在试验范围内的栽植密度与栽植形式的桑饲料价值无大的差异.
Through the study on feed efficiency of 10 different planting forms of two mulberry cultivars and 9 mulches of different planting density in Tongxiangqing and Xinyizhousan, the results showed that: the amount of food, digestion, digestibility, the amount of cocoon, 74% of the test area is not higher than 5%; cocoons layer, cocoon weight conversion rate and production efficiency did not reach significant level, indicating that the planting density within the experimental range and planting form of mulberry feed value is no big difference.
