    New High Yield Cuttings Of Mulberry Trees In Shandong

    New Mulberry Varieties

      A few days ago, Sang Shuxin, a Sericultural Research Institute of Shandong Academy of Agricultural Sciences, was able to cut high quality and high yield. Varieties "Lu plug No. 1 breeding" project has been identified through the appraisal. The root number of the root 1 of Lu plug was strong, and it was suitable for hardwood cuttings. Mulberry farmers used their cutting seedlings instead of grafting seedlings. The cost of raising seedlings per hectare was 2600 yuan.


    At present, the mulberry varieties are generally bred by grafting, but they are laborious and laborious, and the cost of grafting is high. Sericulture industry The demand for low cost and high efficiency mulberry production technology is higher and higher, and the adventitious roots have strong roots. The New Mulberry Varieties with cuttage and seedling raising are of great significance to reduce the cost of seedling raising and reduce the cost of planting.


    According to Chen Chuanjie, a new variety of mulberry, Lu Ting 1 is an Artificial Triploid produced by polyploid technology. It has strong root strength and is suitable for cutting and planting. It can significantly improve the efficiency of seedling raising and reduce the cost of raising seedlings. The cost of rootstock is generally 800 yuan / 10000 plants, and the cost of grafting is 700 yuan / million, and it is 1 yuan by cutting 1 seedlings. Mulberry orchards generally need 20 thousand seedlings per hectare, so the cost of raising seedlings is only 2600 yuan per hectare.


    Because of climate and other reasons, the survival rate of seedlings in the north is generally low. With a year of seedlings, the seedling raising period of 2 years is long. In recent years, planting mulberry in the North generally needs to be adjusted from the south, but the cold resistance of the southern varieties is poor, and the transportation cost of the seedlings increases. Lu Ting 1 has a strong ability to resist mulberry yellow dwarf disease, strong cold resistance and strong root strength, which can significantly improve the efficiency of seedling raising and further reduce the cost of seedling raising. At the same time, the project also pioneered the technology of mulberry under the solar hotbed, and the survival rate of cuttage seedling was similar to that of the corresponding grafting seedling.


    Mulberry leaf is the feed of silkworm. Mulberry Leaf quality has great influence on the silkworm body's robustness, cocoon quality, germplasm, even silk quality and yield. Improving the quality of mulberry varieties leaves to improve the quality of cocoons, silk and silk has always been the goal of mulberry breeding workers both at home and abroad. The results showed that the number of leaves was large and thick, the quality of leaves was excellent, and the results of four silkworm eggs were 1.


    It is understood that the new mulberry variety, Lu Ting No. 1, has now been promoted to 700 hectares, with an area of 1000 hectares, with an economic benefit of 12 million 135 thousand and 700 yuan. In the process of breeding and extension, a batch of specialized seedling farmers were cultivated, which effectively promoted the local propagation and seedling raising ability, and the economic benefits were remarkable.
