Salient features: ● Yield: 2005 2006 516 disease-resistant high-yielding cotton Hebei Department of conventional cotton sowing area test results, the average seed cotton yield over 700 kg, 290 kg of lint in 2007 in Handan, Xingtai, Hengshui latter case even the rain , the seed cotton yield is still as high as 680 to 750 pounds. ● Resistance: The Department of Hebei cotton in the original 516 high-yield disease-resistant anti-blight resistance, on the basis of yellow wilt, after successive years of breeding, disease resistance based on the original, has been greatly improved in 2009 by multi-model a general expression of anti-blight, anti-yellow wilt, seedling does not Simiao, post is not premature. Greenery beauty full of white blossoms. Cultivation: ● balanced fertilizer, organic fertilizer: NPK ratio of cotton required a lifetime of about 3:1:3.5, fertilizer was applied at a certain proportion, conditional block, 1 can chicken Mushi 2 or the 3 to 4 square pig. ● timely sowing: mulching cotton suitable for sowing in mid-April, bare live cotton in late April to May 5. ● Planting density: about 2600 in the high fertilizer and low fertilizer dry thin 3000 3500, no pruning or pruning should be appropriate to simplify Sparse. ● rationalization of control: control before the light after, a small number of principles, generally filled bud mu DPC 0.3 to 0.5 grams, the first flowering to flowering mu 1 to 2 grams, the blooming period mu 3 grams , after topping 5-7 days mu 3 to 5 grams. ● rational dressing: at the beginning of flowering flowering and boll weight applied fertilizer, so that fertilizers with a bell, the top cover of applied fertilizer, combined with Yemianpenfei full insurance cover the top to get high autumn peach. ● timely pruning, topping: one complete pruning, pruning too early malnutrition slow wound healing, too late and too wasteful of nutrition, to better see the flowers before and after pruning, topping the general time July 10 - July 20 ( Once on shore, for at this time). ● timely pest control: bugs Xiang has risen in recent years as the main pests, bugs Xiang features fully understand in order to better control, the other as spider mites, aphids and other non-phosphorus homopteran pests, to prevention and treatment.
