Key Technologies for Raising Seedling rice

Urine lOOkg, SSP 1k different, but 0.2k different chloride, urea 0.5kg, plowed 23 times. To promote the full integration of soil and fertilizer, leveling Zuoqi (Qikuan 1.3m, car groove width 40cm, Wai Goushen 40cm, Qigou deep 10-20era). Wow do soil surface broken, Ping net, seedling bed ratio of 1:40 and field (each field to be the seedbed l5m2 667m ~ 561 holes or plastic disk about 50-6o beds). 1-2 days before planting, each with 50% of the enemy leaves turning green stage, jointing stage, each one l5 667d 100 tons of medicine, water 80 ~ l00kg, the full mix, along ridge irrigation in the wheat stem base. ③ visual severity of irrigation were treated roots,UGG ブーツ, light clover fields of disease from time to spray. (Ae National Rural Well TECHNOLOGY seedling basis. on the land has irrigation facilities, irrigation measures can be used to supplement soil moisture; and cotton fill Dry moisture, mainly by ground water and natural rainfall supplemented, but more by the potential depth of groundwater and rainfall time, rain affects , by natural factors. dry and water-saving cultivation techniques are still the basic technology of water scarcity regions, while the plastic film covering the ground soil moisture is also the current dry cotton and effective measures, according to the hydrological characteristics of different dry areas are the following : First, the regional groundwater use is low,UGG ブーツ, Huang Ling winter plowing or plowing, harrowing film Lao soil moisture. application of winter plowing or top of the Ling Gengba in a way which is conducive to the soil cooked billion, and to accept the snow and rain in winter and spring is to solve the water shortage as early as in one of the measures. .5 g 2 spray water on the water bed, the soil disinfection to prevent the disease Simiao. Second, the sun soaking germination, the seeds after the election after disinfection by drug Jing. soaking primed. due to variation in temperature in early spring, germination technique difficult to master, Ling suggested the use of soaking soaking,ghd glätteisen salon, each (2ra1) soaking liquid water lOkg 6kg, soaking IO-I2 hours. breathability 3-5 hours. continue to use water immersion for 12 days. will suck enough water in the drain and under the conditions of seed preservation ( 32c) germination, 90% to be spread out to dry after breast bud break, when you can start is kind of root dry nursery sowing, germination should not be too long. Third, the planting of early rice rotation systems according to our type of climate Ha production practices, fallow fields, green manure crop, should be in the end of March to early April before the dry nursery planting, rapeseed crop should be in April I5-20 日 dry nursery planting seedlings to guard against over-age, generally every dry nursery, planting about 25 duh, plastic disk about each sowing 7Og . to be elected the first rush of cold end of warm sunny planting, sowing the day before. seedbed flood drenched several times, so that the soil wet Qimian 10-15em; planting to absorb, broadcast to the plot edge, to promote the quantitative plate by seeding down the valley Gently press the seeds after sowing buried on three sides, alternate cover 0.5em thick cover seed sifted soil, jet wet. cover seed soil can not be too thick or too thin. must be mixed with soil is not the library of any fertilizer. plastic plate dry supplemented in clinical education watering before sowing the seedbed surface made of mud-like (paste), the plastic tray seedling bed flat on the surface of soft reduction, and the beds so close, should not vacant; affect seedling, first in plastic thrown into the tray I / 2 nutritive soil, according to several species of uniform sowing bud blame. and then make up the remaining 1 / 2 of nutritive soil, sweep the disk in order to avoid species of root death House. wet the surface. the beds covered arch Gongpeng , insulation and promote long. Fourth, management seedbed sowing to seedling stage, film temperature control at 35. C, leaf leaves stage, film temperature control 25C or less,p90x calendar, over-temperature two Removing Film ventilation and cooling; use of fine weather at noon removing film, each with MET 0. 15og spraying water. laminating spray Zhan; the second leaf stage. film about temperature control in the 20c. to keep Chuangtu dry leaf one, every corner Jinchu 15-2 with urea, potassium dihydrogen phosphate log on 3kg of water spray, Shi Houqing washed seedlings,p90x workout calendar, prevention and control of damping-off (with the enemy per lkg of water spray Nixon 1E); clover when removing film ventilation of buildings should be hardened. removing film in a little after the first big , at exposing the night cap, or if there l2c cold front through the following low temperature. need to spread straw mat in the membrane temperature by 3.5 leaves all the time removing film, when the rain Ha tectorial membrane to prevent rain, do not seal around the maintain the early blind state. promote the root under the bar, in principle, not watered leaf, seedling age 25-28 days, leaf age 4.5-5.5 leaves, height about buildings were transplanted 15em; planted 3 days ago . the wedding of fertilizer topdressing. Each of urea 30g, potassium chloride peak water 3-5kg, wash with water pouring Zhan Shi Miao, is not resistant to bacterial blight, rice blast disease in variety selection LO Pharmacy prevention. to do with drugs Under the field with fertilizer. * 7 -
