Wheat and soybean seedling dry stubble mountain transplanting techniques


High-yielding varieties longer incubation period. To dramatically improve yield. 13 saves with the species. Conducive to the popularity of early varieties of soybeans after wheat intercropping live, in order to ensure the planting density, need to increase seeding rate. General seeding rate per hectare of agricultural science in the 28 North HUBE] AGR] CULTLrRALSCIENCESNo. 4,199875 above. Transplanting taken, only bean seeds per hectare is about 20. Decline with the species, types of cost share be reduced accordingly. Thus many farmers may be updated to promote improved varieties, selected seeds. Improve the overall quality of the seed. 14 good planting environment. Seedling growth of soybean seedlings to improve the quality of a good or not, directly determines the late soybean production. Lack of self-fixing soybean seedling ability to grow well, there must be a good temperature, light, water, fertilizer conditions. Wheat and soybean stubble early to grab stubble if live, it is difficult to create a good environment and soil fertility, seedling emergence after shaded by the corn, resulting in tall seedlings, line seedlings. To seedling transplanting. Nutritive soil or plastic bowl with a floppy disk breeding system, selection of light, water and fertilizer concentration of nursery land in good condition. Fine management, not corn before the shading, soybean seedling growth to create superior environmental conditions. 1.5 bar under the control of root and stimulate the growth of soybean lateral roots especially strong absorption of water and fertilizer root absorption capacity,[link widoczny dla zalogowanych], mainly living in the soil in better water and fertilizer. Although soybean live help to promote deep root down the bar, increase drought, but the mountain early in the general shallow topsoil. Intercropping and drought conditions on the relative decrease in soil layers. Roots on soybean yield depends on activities of soybean root mass in soil quantity and capacity of absorption of water and fertilizer. To seedling transplanting, although the injury r root when planted, but the root can stimulate the inside of a large number of occurrence of topsoil, water and fertilizer to improve the absorptive capacity of soybean. Moreover, r the permeability of the soil layer of soil a good development and nitrogen fixation of rhizobia increased activity, which can enhance the ability of soy itself for ammonia. 16 to ensure the rational close planting. Dryland wheat stubble to increase growth uniformity is difficult to ensure a reasonable density of live and high uniformity. To seedling transplanting. Plenty of time. Can be intensive, consistent with a large selection of strong growth and tidy transplanting seedlings. If the moisture after transplanting appropriate or timely watering, the general survival rate of 98%. To ensure reasonable density, a full planting seedlings, and strive to yield. Intercropping soybean seedling transplanting 2 2.1 key technologies to choose suitable land. The best selection of superior varieties of moderate slope, deep soil, high fertility, water easily block. In the selection of varieties on the one hand, should adopt the longer growth period, high yield potential of more dog breeds; the other hand, the selected varieties should be more water-fertilizer, branch development, growing strong, higher productivity per plant. Seed selection should also do the work,[link widoczny dla zalogowanych], make full use of temperature and light resources, lower density conditions to ensure adequate and stable yield,[link widoczny dla zalogowanych], high yield. 2.2 Preparation of fertilizer early bowl system, sowing in sterile seedling fertilizer should be prepared early, the best quality of manure mixed with appropriate amount of loam mix in the month before sowing the full stack steep maturity, reduce the number of pests and pathogens. Mortar and sowing can be made at the same time, while manufacturing and broadcasting; also be made ahead of time in the labor abundant good seedbed mulching in alternate rows. Sowing time and then poured enough water to be run through nutrition pot full of water after planting. If the conditions,[link widoczny dla zalogowanych], the best nursery plastic floppy disk to save labor and improve transplant efficiency. Shorten the time to turn green. 10-20d in the wheat harvest before planting, with 1 to 2 leaf transplanting. Planting too early, if not timely transplant. In the seedbed prone to tall seedlings. Late sowing,[link widoczny dla zalogowanych], seedling transplanting technique can not be fully effective, and the seedlings are too soft, Wan Miao Miao easily hurt when Zaimiao. Nurturing seedlings. First, the bed can be covered by wet straw and other measures to ensure the seedbed at any suitable temperature and humidity. Too dry to prevent bacteria bed. Second, after sowing, or playing with the old film L film adequate coverage to prevent insects, rats, birds, harm, while preventing burn seedlings. The third is a true leaf after Qimiao time. Paclobutrazol sprayed i00rag/kg seedbed to facilitate the nurturing seedlings, trigger branches. 2.3 robbed when site preparation, proper moisture given promptly after wheat harvest from transplanting to grab moisture will be plowed. Loose soil moisture storage and then broken mattress. If the drought, nor watered conditions, can be used instead of tillage stubble to prevent the running entropy. Land leveling, the time predetermined spacing hit points. Discretionary per hole depending on soil quality of manure and fertilizer were applied, controlling the amount of fertilizer per hectare in the manure 30 - 40t. Compound 150-200kg. Transplanting soybeans, because production capacity per plant significantly increased, thus planting density should decrease, generally based on the density of conventional broadcast 1 / 2 an i / 3 plant (soybean stubble mountain upland intercropping, the use of a Jufeng soybeans per hectare density control can be 4 to 50000). If the lack of moisture during planting, set the root water pouring side linesman, usually up to a whole seedlings.
