In recent years, vegetable farmers in Binhai County, Jiangsu Province have used dwarf pod-like high-yielding techniques to cultivate sassafras buds, which has doubled the yield and benefits of sapling buds. Toona sinensis buds are the young leaves and tender buds that have just sprouted. They are traditionally famous and excellent vegetables in China. It is favored by people for its rich nutrition, crisp and juicy, aroma and delicious. With the improvement of the people’s living standards, the demand for Toona sinensis as a high-grade vegetable is increasing day by day. In recent years, due to the good economic benefits of cultivating scented buds, in order to increase the yield of sassafras buds and to facilitate the management of picking and intensification, we must first create saplike dwarf forests for the purpose of producing toona sinensis buds. Therefore, a set of practical high-yield cultivation technology of dwarf bud clusters is introduced here for reference. I. Variety and density Black oil clams, red oil clams, cyan oil clams and other fine varieties are used. Using dwarf plexiculture, seedling height 1.3-1.8 m, seedling diameter 1.8-2.5 cm, 6 plants per 1.1 m2, hexagonal plexiform, 600 plants per 667 plants, 3600 plants in total . Second, the first year of management 1, soil preparation fertilization. For every 667 667 tons of soil-fertilizer in spring, 4,000 kg of ammonium bicarbonate, 30 kg of superphosphate, and intensive cultivation. 2, breeding time. Before and after August each year, it is the best time to propagate the seedlings cultivated with citron. The method is to lightly plan under the ash tree, select a lateral root with a diameter of 3 cm or more, saw the root from the root, and slowly bend the root of the saw to the outside of the ash tree (note that the main root of the tree does not move) . After 15 to 20 days, the cut seedling roots will grow seedlings from different parts. These seedlings are cultivated and used for planting in the coming spring. 3, planting time. In the middle and late March, the seedling roots were soaked in 40% carbendazim 400 times for 10 to 15 minutes, and planted, watered and earthed according to design requirements. 4, cut dry buds. When the seedlings grow to 30 to 40 cm, the top buds are cut off, and the trunk is kept 15 to 20 cm. After germination, 3 sub shoots per plant are left and the rest are erased. 5, control the height. (1) Topping up. When there are 3 pairs of 20 cm pinnate leaves in the shoots of the new shoots, the upper shoots are removed and the secondary shoots are promoted. 4 to 6 months to pick the heart 2 to 3 times. Each time after picking the heart, two new shoots are left to form secondary shoots. (2) ring cut. From the beginning of May to the end of June, take a ring cut on one tip and cut it every 10 centimeters long, for a total of 2 to 3. 6, top-dressing watering. From May to July, 20 kg of urea was topdressed for every 667, followed by 2 top dressings and watering after application. 7, control growth. Plant growth inhibitors are used to control growth. From the beginning of August to the beginning of September, a concentration of 3031-6 ppm 333 was sprayed every 10 days, and sprayed 2 to 3 times. 8, pest control. With 70% thiophanate-methyl 800 times control root rot; with triadimefon prevention and treatment of rust; with fast-eliminating chrysanthemum vinegar, omethoate and other pesticides by conventional spray control of moths, ulnar plover, Plasmopara of wax and other pests. Third, the second year of management In March, 10 kg of urea was applied every 667 hr. After application, the mulch was covered to achieve early germination. In mid-April, after picking the toon buds, 20 kg of urea, 50 kg of superphosphate, and 4,000 kg of mixed fertilizer were applied every 667 tons. After the application, the fertilizer was turned into the soil and covered with plastic film after watering. The mulch was removed in mid-June. After the shoots were grown, each shoot had 2 to 3 new shoots, and the others were wiped off in time. In late June, the growth of new shoots was controlled with 1 g of dildo-amine water and 75 kg of foliar spray every 667 hrs. The spray was sprayed every 10 days for the second time, and sprayed for the third time in early August. Fourth and third year management After the harvesting of the toon was completed, the trees were immediately flattened, and the lateral roots of the original trees were cut off appropriately, and the root shoots were promoted. At the same time, the fertilizer was fertilized and watered every 667 tons of fertilizers for the second year. When the seedling grows to 40 centimeters, the first picking is done and the length is kept at 30 centimeters. The second picking was performed at a time when the sub tip length was 30 cm, and the length was 20 cm. Other management measures were the same as the second year. The density of 3600 plants per 667? was retained. Excess roots were dug out and transplanted elsewhere. YT-88 YT-88 Shenzhen Sunshine Technology Co.,Ltd , https://www.szyatwin.com
