(the complete word version) the technique of sank tree cultivation is a choice of techniques to grow sank land: all types of land can be planted, including water fields, slopes, river banks, etc., but it is not appropriate to plant it directly in low-lying areas with long-duration water and in former lands with ailments, cyanosis, root worms, and sanctuary plumes. 2. Selection of good seedlings: currently, the main species of guangxi sang trees are those nos. 12 and 62 and no. 2, which are of high quality and high yield, and are the preferred species for the vast majority of farmers. 3. Rationalally dense and fast-growing: common silk-bearing sanctuaries are suitable for planting density of about 5,000 plants per acre. Single-line planting: 70 to 80 cm, 15 to 20 cm; double-line cultivation: 90 to 100 cm, 40 to 50 cm, 15 to 20 cm. It's about 7,000 acres per acre. The scientific method of combating foliage, which is the main pest and pest of the san tree, is 50 to 70 cm long in winter, effectively preventing the occurrence of foliage. (2) bacteria blackness: 10 kg of water with 5 grams of thurcin or 1 gram of agricultural chain cythin with 10 kg of water sprayed, stinged and sprayed once every seven days after safety period of 1 day. (iii) palsy: sanctuary quarantine, prohibition of the use of seedlings; several years of rotation with grasshoppers; removal of strains, isolation of trenches, reduction of morbidity and spread. (4) chrysotile disease: new sprout leaves sprayed 1,000 times more frequently with 25% rusty pyro-wettable powder, with one blow in seven days and seven days after safety. (5) powder disease: 100 times more tobuzin or 70 per cent more than 1,500 times more in kitobuzin, with a 10-day break of one and a safety period of three days. (6) purple plume: the strain is found to have been dug and burned, 0. 4% formaldehyde is disinfected in the pits and severe plots should be rotated for several years. (7) cyrethroid disease: 80% dbcp 100 times the liquid root, 3-4 kg or 20% wilaya sangen per acre, 4-7 kg per acre, and water after application. Seven days after the security period. (8) samsun horse: one in five days' time, with 700 to 1,000 times the weight of 40 per cent fruit or 1,000 times the amount of 80 per cent diarrhea, or 40 per cent with 80 per cent diarrhea 1,000 to 2,000 times. The security period is five days later. (9) sanphthalms: 73% khd 1,200 times more than 10 days after safety. (10) sanctuary: 1,000 to 2,000 times more than 80% of the enemy, five days after the security period. (11) sanctuary: 1000 to 2,000 times the diarrhea for 80% of the duration of safety. (12) slashed night moths: 5,000 times the value of 90% of the spirit, 15 days after safety. (13) salvatore, salvo lice: 1,000 times 40% of fruit plus 80% of diarrhea 1,000 to 2,000 times, five days after safety. A full and timely supplementation of chemical fertilizers at n:p2o5:k2o ratio of 2:1: 1: n2 kg, p2o1 kg, k2o 1 kg, per 100 kg of saliva produced. The fertilisation of the leaf is carried out twice, first (first half year): 1,000 to 2,000 pounds of organic fertilizer in acre, 150 to 200 pounds of urea (15:15:15) or 100 pounds of urea and 150 pounds of phosphorus and 50 pounds of potassium chloride in acre (15:15:15) 150 pounds of urea or 100 pounds of urea and 40 pounds of potassium chloride in a second (second half). It is important that those who adopt a san harvest insist on making san and fat. Four
