Liao Kui hybrid sunflower hybrid seed technology II

75000 / hm. . Seed sowing is slightly higher than the re-broadcast production though, but the overall economic benefits as multiple cropping. Because now is the sowing of sunflower flowering Hamilton filling the hot season, many burned by the sun disk Kwai, seeds will be mature bird feeding. Cropping system can avoid these kinds of hazards. 4 intensive, pay close attention to farming system Miao Qi Miao strong enough base fertilizer should be applied. When manure is broadcast 45 ~ 6Ot/hm,[link widoczny dla zalogowanych], DAP 225 ~ 300kg/hm. . Seed sowing time to the complex organic fertilizer, P fertilizer before sowing must be 225 ~ 300kg/hm. To ensure that the needs of sunflower seed on the phosphorus. Practice has proved that fertilization of sunflower seeds, high yield, grain full. Entropy foot irrigation water, fine soil preparation is to ensure that all seedlings, robust key. Are sowing seed moisture should foot irrigation water before sowing, cropping or seed production should be early in barley wheat harvest 5 to 7 days before the current 5 2000 237 * good water, irrigation Jiaotou absorbed attention, before the harvest rush entropy alone field. Plowing depth of 16 ~ 18cm, be the horizon, thin soil, good soil moisture. Improve the quality of planting. Planting techniques and planting quality, relationship to the seedlings all, Miao Zhuang and seed production, must be fully and well. CMS is not resistant to downy mildew, especially in areas of summer rain, the application of 0.3 metalaxyl (Swiss drug mycophenolate) seed dressing. Planted to the best east-west line of artificial demand, and 2 to 3 capsules per hole planting, sowing depth 4 ~ 5cm; with machine sowing, and seeding rate, CMS 10.5kg/hm. Restore the system 9kg/hm. . Sterile seeds small, local broadcast cooked dried after addition of barley or wheat 10.5kg/hm. , Mix planting, so sow the seeds evenly recovery system should be added a small amount of seed corn or soybean crop marking. Sowing machines should pay attention to planting depth, weak sterile top soil, sowing depth 4 ~ 5Elm, restorers kernel size, strong top soil, sowing depth 5 ~ 6cm. To ensure that excavated seed germination, sowing should pay attention to suppression of Mo in soil moisture strict roguing ensure seed quality seedlings 2 to 3 pairs of true leaves appear, the combination of thinning thinning seedlings, Dingmiao of seedling plants seedlings in the high line, mast (black) seedlings, seedling disease, removal of all abnormal seedlings, seedling row height looks the same. Between the lines of sunflower seedlings in the seedling stage must be divisible. Bud stage with cultivator fertilizer, branch line of our parents, the tall plants than at any time set aside, so that the entire field line height and tidy, the spacing of the parents to reach the required standard. Flowering farming system should be fixed by professionals, in the 8 to 10 every morning, the parents carefully check the situation of the flowering. Bank of the mother to be progressive, it was discovered loose powder line,[link widoczny dla zalogowanych], to immediately remove face plate and the end of the disk button on the ridge. Contour lines for the parent of the Bank,[link widoczny dla zalogowanych], diseased plants, tall plants should take off button on the ridge at the end faceplate to prevent pollen contamination. The Bank should be harvested before the female line by line, by the first check on the hybrid strains, strain, complete removal of abnormal strains. 7 5 strengthen the management of fields and pollination management to highlight an Began after emergence, seedlings should be replanted in time check, where the ridge off Seedlings Deficiency, Park species should be promptly take appropriate measures to ensure the emergence. Sunflower grows to 2 to 3 on the leaf when the thinning thinning seedlings, so that no cluster 4 to 5 pairs of true leaves seedling when Dingmiao, so that the standard Dingmiao, leaving about 50cm high when the two-Miao Miao, conduct a cultivator ,[link widoczny dla zalogowanych], cultivator depth of 10 ~ 12cm, do soft soil, field weeds. With cultivator, topdressing urea 300 ~ 525kg/hm. . Artificial fertilizers should be applied in line dressing room, so as not to burn seedlings. Common sunflower bud and start flowering when the first irrigation water. If the seedling soil water deficit, seedlings have been affected and shall promptly poured the first water. Loose soil after watering or cultivator to be timely. 3 to 4 times the whole growth period pouring water. Flowering to filling stage to keep the soil moist state, to ensure strong and full. Pollination can increase seed rates to increase seed production. Pollination by bees, the general 1hm. To put 1.5 to 2 boxes bees. Bees should start flowering sunflower farming system to move people, to ensure the timely seed pollination. In the absence of bee source case, the implementation of artificial pollination,[link widoczny dla zalogowanych], the flowers began to bloom period, with the puff method of artificial pollination. When you do not break style pollination, or affect pollination. 8 seed harvest and storage when harvested at full maturity. Received the first female harvest, and then close male. Parents harvest drying of the Kwai disk to breakout, single income, single-drying, singles, cut suddenly mixed. Kwai disk before threshing and then check the female parent, the hybrid inferior, deformed Kwai disk should be eliminated. Kwai panel focused on playing, should be promptly shared drying, threshing. Do not heap moldy and rotten, causing losses. Dried promptly after threshing, water content not higher than l1%, after selected by the selection of bagging machine bags of people inside and outside the library should be placed labels.
