Canopy may be appropriate to reduce the weed after the number. (4) pruning: Timely pruning can improve the quality of the trunk, stem form conducive to fostering high-quality good timber. When planting seedlings to repair all the lateral branches, 1 to 3 years after planting the saplings, removal of competing branches. Reserves and auxiliary support branch, and cut off the trunk at the base of the sprout, develop a strong upright trunk, crown pruning intensity should remain the ratio of length and height of 3 / 4 or more. Four years later the trees on the repair in addition to the gradual growth of weak lower crown branches, the crown length and tree height remained the following ratio: Height lOm above, crown height than 2 / 3; tree 20 meters high, crown height to 1 / 2; tree height of 25 meters to ?, crown height to 1 / 3. (Author: 055,750 Nangong Vocational Education Center in Hebei Province) strain of maize reduced by the high density super high yield method for a Ru Jiang, organic manure fertility to achieve sustained high yield of maize, soil fertility is the foundation. 3-5 square manure applied per acre, manure and other organic fertilizer. Can increase soil organic matter, improve production conditions, soil fertility, improving land quality. Second, promote the root Ridge Planting Subsoiling should Previous Crops planted land after harvest, timely operations of subsoiling subsoiling depth of 30 to 35 Ha meters. After the use of heavy harrow rake pine through, rake thin, broken rake. Sowing in low temperature, 30 cm before planting ridge to improve ground temperature,<a href="http://www.toryburchsoutlets.com/" target="_blank" class="postlink">tory burch outlet</a>, to the purpose of Zhuang Qi Miao Miao. Third, timely sowing seed supporting ultra-high density-resistant varieties of the constituency-type varieties, such as Cheng 958, 335 and so the first Yu-density tolerance varieties. Artificial selection before sowing the seed, remove the broken grains, insect food grains and grain lesion in order to ensure seed germination and purity. Can be used before sowing seeds of maize seed coating amount of 1.5% by seed dressing. Northeast District Spring corn the best sowing date of April 20 for a May 10, such as planting too early, could easily lead to bad kind of low, uneven emergence; such as planting too late, it will affect maize growth and post-dehydration. Planting shall be based on soil moisture and temperature conditions to determine the spring sowing depth, suitable for sowing depth of 3 to 5 cm. When sowing seed rate increased 10%, generally sowing of 4 kg,<a href="http://www.ralphlauren-outlet.net" target="_blank" class="postlink">ralph lauren outlet</a>, Ultra-high-yield field can increase to 5 kg, 5 leaf stage pulling weak seedling, leaving the seedlings to ensure uniform seedlings, Miao village ', Miao Qi. Fourth, increase the density of building community to achieve high yield over 1000 kg per mu, ultra-high levels, must be suitable for close planting,<a href="http://www.mbtshoessales.org/" target="_blank" class="postlink">mbt shoes sale</a>, the density to 5,000 plants / acre to E, according to species characteristics and soil fertility levels to determine the appropriate Liumiao density. Zheng 958, per acre must be left to} =. 6500 , Paid no less than 6000. Yu Liu Miao 600O first 335 lines per acre, paid no less than 5500. Planted way, 6o cm row spacing, plant spacing 18.5-20 cm. Five strains of chemical regulation strong stalk lodging reduction of production and test results show that the general density of more than 4500 varieties of corn, acres of field prone to lodging when the phenomenon. Application of chemical control techniques, jointing stage in corn sprayed 300ppm Zhuang Feng Jin Ling was music or other corn regulator can achieve reduced vegetative corn, straw thin stalk Kennedy, lodging, and does not change the Ear, building The purpose of high-yield group. VI, precise and high yielding fertilizer generally high yield production of 100 kilograms of grain needed per application of 3 kg of nitrogen, phosphorus l kg, 2 kg of potassium. Maize yield field must Mushi nitrogen (urea) 5O kg, phosphate (SSP) 50 kg of potash (SOP) 25 kg per acre for the land should be applied on zinc deficiency zinc sulfate l kg. Operations on the fertilizer, light Shi Miao Fei, Shi panicle weight, make chase to spend Li Fei. Miaofei before jointing in corn by about 30% of total nitrogen plus all the phosphorus, potassium, fertilizer, seedlings along the side of open Goushen facilities (15 ~ 2O cm) in order to promote root seedlings. Panicle large bell in the corn phase (1l ~ 12 leaves to expand) 5O% Total Nitrogen topdressing around in order to promote more big grain panicle. Flowers Lifei topdressing nitrogen during grain filling volume of 1520% in order to improve the photosynthetic capacity, increase grain weight. Seven, to prevent and pest control insurance income producing corn diseases, pests lot, disease control first, to combat resistant varieties by selection, such as the size of the leaf spot, stem rot, etc.; the second is to adjust the sowing date, reduce planthopper damage, prevention rough dwarf virus disease. Soil pests by Seed or seed dressing to control packet, corn in the large bell of organophosphorus pesticides used to control. Eight, live broadcast late harvest yield strong seed corn, sowing depth 3 to 5 cm,<a href="http://www.uggssonline.com" target="_blank" class="postlink">uggs online</a>, the same depth to ensure that seedlings Qi, Miao full, uniform seedlings. When the corn husk in the Daejeon, white, yellow, the grain filling has not stopped, the appropriate late harvest, late to the corn kernel milk line disappears, the black layer appears dry loose husk after harvest when the fully mature, can increase the grain weight, increase production.
