Low wet clay, maize cultivation techniques
Low nutrient ratio is not quite ancient coordination, there is no guarantee early seedlings, the blade mantle, mid-fat trend strong enough stamina. Garden constrained by natural conditions is strong, but not ear corn production year low. I stand to stay in 1990 the establishment of village and other towns. Low wet clay, cultivation of maize yield,nike shox, area of 2 hectares,nike air max, after three years of experimental research, in the autumn of 1992, municipal leaders and economic rather special plug-site production acceptance testing, 2 acres of maize average yield of 058.05 kg, compared with the previous three years development and testing (1987 ~ 1989) Average Muzeng 183.05 kilograms, an increase of 38.5, three former times for a total yield 7.7 million kg, ■ promote the cover flap defended Tony Sang (a) of the entropy of a good island Kui technical measures to ensure the whole potato seedlings for a clay barrier to planting seedlings after taking a major problem. To this end, in the autumn when the wheat species into species the size of the line, accusing him of a single 30 cm, small 2o cm row spacing, intercropping maize lines as the big firms, to facilitate mechanical sowing, sowing rate of increase in the region {try intercropping maize with both Mo 1219 to facilitate appropriate time to focus on planting soil moisture, improve planting quality, well built motor-pumped wells to ensure that the area density of 465 I rat. L7 seat with both hands Xinjiang station network, reaching double-well station facilities, making no tuo moisture before sowing,moncler 2011, or pouring Fan head of water, 3 to 5 days to complete. , (B) In former times when the stubble Zha earth, jealous deter most living soil after wheat harvest repeated 7 days if no rain, the surface hardening, cracking, staggered, such as useless to pull off the young roots of seedlings. This is the root of the heap of new clay to pre-made vaccine and the blade is no guarantee that one of the reasons slower. To this end, must be within 5 days of stubble tillage after wheat harvest, and make it a live soil protection layer, soil moisture, protect roots, seedling protection again and again if the soil water after wheat field water holding capacity of more than 80% of music, the lack of soil air Wei step, seedlings by the collapse, Miao Miao Huang weak, which is pre-made one of the reasons Tony slowly. So when the Man Yuan drainage and increase soil permeability. Promote root seedlings. Man of clay in the low ground. Anti-ulcer and on the high ground water drought protection, and seedlings as important as (c) morning to promote early recovery is the re-chase Miaofei 5 can be seen in the corn leaves before, with heavy stubble early chase chase Miaofei, by foot and P and K fertilizer, ammonium bicarbonate per acre foot chase 5O kg, the total amount of fertilizer 30 ~ 4o, which is pre-made solution to seedlings slow clay, the main measures to promote early-onset foot. =, Built with a compact high-yielding varieties, high-density compact selection of Tibetan culture yield varieties, according to the maximum density requirements of different varieties planted. Development of experimental field in 1992, 2 acres,ghd haarglätter, planted 4 varieties, and throw into confusion Yedan single l2 number, three factors constitute the level of production is 5674 t mean mu spike Lei, Lei 454.8 grains,ugg boots italia, grain weight 300 grams per mu (85 discount) 658.05 kg. Third, increase the investment amount of fertilizer, soil fertility species in the autumn before the adoption of soil testing, fertilizer guide. Test in the autumn of 1989 the amount of nutrients in the ancient (weighted average) 1.27, organic matter, nitrogen 54mR/kg, available P 6.2mR/kg, speed boats potassium 128rag/kg, soil damage weight 1.21g/cm. Fat in the foot, take organic fertilizer, heavy P fertilizer, the fertility measures spin potassium supplement. When each species in the autumn. Exploration farming 20cm above the base acres of high-quality manure applied from 3000 to 4000 kilograms, Ca Pi speech fertilizer 5o kg, 20 to 30 kg of potassium sulfate, ammonium bicarbonate to recover 50 kg of corn per acre is t Miaofei number of acres of blue-foot high-quality manure 2000 ~ 3000 kg ammonium bicarbonate mu 5o kilograms of fertilizer Lei Lu} 80 ~ 100 kg of ammonium bicarbonate, prior to the date in the big horn, Age 50 to 55 during the chase advice completed. Topdressing Lifei few blocks. Furthermore, each year more than 300 kilograms per mu of wheat straw (including high stubble). In the fall of 1992, Yi-min test than the soil has been significantly improved before the development of organic matter of 1.30, alkali fluoride 74mg/kg, build efficient speech 12.8mg/kg, K 130mg/kg. Heavy soil density decreased 1.199/cm. ] Fj 『f · 27 · |
