Introduction of Guisang No. 6

1. Features

It is a triploid hybrid mulberry.

The plant population is neat, the tree is tall, the branches are upright, and the clockwork is many. The branches are tall, medium thick and straight. The skin color is blue-gray, the nodes are straight, the pitch is 3.9-5.3 cm, the 2/5 phyllodes, and the lenticels are oval. Or round, small, medium-density, winter buds are equilateral triangle or long triangle, gray-yellow, sharp and adnate, with accessory buds but not many.

The leaf shape is full-leaf broad-heart shape, dark green in color, relatively flat, the tip is short and tail-shaped, a small amount is double-headed, and the leaf edge teeth are papillary serrated, medium in size. The leaf surface is smooth, wrinkled or wrinkled, and has strong luster. The leaves are mostly flat, with short stalks, and shallow heart-shaped leaf bases. The leaves are large and thick, with a leaf length × leaf width of up to 30.2 cm × 26.8 cm, and a single leaf weight of 10.9 grams.

The top buds and young leaves are brown-green. 90% of the plants have female flowers. There is a hibernation period. In Nanning, the sprout time of winter buds is early January, and the growth period is long. If there is sufficient water and fertilizer, the leaves can grow blindly until the end of November.

It is resistant to cutting, suitable for harvesting from leaves, and also suitable for harvesting of mulberry all year round; it is resistant to drought, high temperature, and has strong adaptability.

Test performance: From 2013 to 2014, regional tests of new mulberry varieties were carried out in Xixiangtang District, Yizhou, Huanjiang, Liucheng, Napo, and Zhaoping of Nanning. The average yield of mulberry leaves was 2390.1 kg per mu, which was 2× The yield of Lun 109 increased by 13.60%; the second year of production entered the high-yield period, and the average yield of mulberry leaves per mu was 3316.5 kg, which was an increase of 13.48% compared to the control Sha 2×Lun 109. Leaf quality: The average cocoon layer of the three batches in spring, summer and autumn is 98.92% of that of the control Sha 2×Lun 109; the yield of one hundred kilograms of leaves in summer leaves is 4.29% higher than that in the control, and there are 3 batches of spring, summer and autumn leaves. Compared with the control Sha 2×lun 109, the yield was increased by 2.55% on average. Resistance to mulberry mosaic disease: the incidence of mosaic disease was 19.99%, and the resistance was 14.27% higher than that of the control.

2. Cultivation points

1. Use seeds to propagate. The seedlings can be planted first and then transplanted to build a garden, or they can be broadcast live to form a garden.

2. Suitable for dense planting and felling. Planting 4500-5500 acres. Mulberry groves are harvested mainly for leaf harvesting once a year in summer and winter. The summer cutting should be low or root cutting, and the winter cutting should leave long branches (leave half-year-old branches with high 30-50 cm), promote early and fast growth of winter buds, increase yield and leaf quality, and prevent mosaic disease.

3. The mulberry garden should apply more organic fertilizers and topdressing in time to promote lush foliage and exert high-yield performance.
