Measures for cultivating: 1 cultivating and weeding, usually 2-3 times, when the summer solstice is small The lotus leaf covers the surface of the water until it is “sealed.†2 Dressing: 70% for lotus root basal dressing, 30% for topdressing, separate topdressing of leaf and manure, and topdressing urea 20kg or human feces in 3-5 main leaves. 20-40 urine urine, in the main leaves Man Tian chase compound fertilizer 30kg.Two, white wolfberry cultivation techniques 1, select varieties: a familiar wolfberry, the main varieties are: cold head lice, ivory lice, a little red, large seedling lice. There are mainly Xiaolatai, 79-1, 8602, 80-1, etc. 2. Site preparation basal fertilizer: choose sunny, fertile soil plots per acre Shifen 100 110. 3, transplanting: spring and autumn planting.Spring planting: I County in the middle and late April, spacing 0.65-0.7 meters, 1200 points each Zhou.Farming: early July to early August, walking 0.4-0.33 meters, 4000 points per mu 4. Field management: 1 Water level regulation: The water depth of the new Putian during the tillering period is 3-4 cm, 7-9 cm after the tillering stage;2 Reasonable fertilization: follow the former 8 weights, medium and light, after Heavy principles; 3 cultivating and weeding: cultivating 8-10 days after living stems, cultivating 2-4 times, removing weeds in time, combating stems and leaves; 4 management of old hoetians, wintering management: cutting mud after harvesting The stubble, remove the male and male piers, shallow water 1-2 cm.Spring management: 1-2 cm shallow water at the time of germination, 60 lbs of feces, and 60 lbs after January. 1. Selection of improved varieties: There are mainly Wuxi Shuiqin and Yangzhou Changbaiqin: 2.

Field management: 1 Weeding seedlings; 2 Water level adjustment: 10 cm in seedling height When soaking 4.5 cm around, after gradually deepening, up to 80 cm; 3 fertilization: 80-100 basal manure before row seeding manure, when the seedlings excrement 20 urine, Wang long-term application 30-40 Tam, top dressing The first should be drained water.Fourth, solid cultivation techniques 1, species selection: There are mainly alfalfa and white peony, white peony is higher than the yield of alfalfa, good quality, 2, sowing and nursery: 1 live in early April, The sowing is suitable for cultivation with a large area of ​​water depth.
