The application of controlled release fertilizer special for cotton of the present invention is to be that base manure once applies at the sowing cotton seed previous crops, no longer imposes.Excellent results of the present invention is as follows:
1. the nutrient reasonable ratio studies show that, every production double centner cotton gined cotton needs 13.13 kilograms of absorbed nitrogens, 4.57 kilograms of Vanadium Pentoxide in FLAKESs, and 13.13 kilograms of potassium oxides, the ratio of nitrogen, phosphorus, potassium is 1: 0.35: 1.According to this assimilation ratio, nitrogen, phosphorus, the potassium ratio prescription of controlled release fertilizer special for cotton design are 1: 0.35～0.59: 0.61～1.01.This prescription is applicable to the most of edaphic condition of China, and middle-and-low-yielding fields can suitably improve the ratio of nitrogen, and the high-yield field should increase phosphorus, potassium ratio.Because the order of middle-and-low-yielding fields nutrient deficiency is nitrogen＞phosphorus＞potassium, and the high-yield field is because fertile soil, the cotton plants riotous growth, and the field ventilation and penetrating light is poor, causes disease easily.Phosphorus, potash fertilizer particularly potash fertilizer have the cotton plant of promotion stalwartness, the effect of disease resistance enhancemen.
2. the controlled release fertilizer nutrient discharges with the cotton absorption and matches according to the study, and cotton absorbed nitrogen, phosphorus, potassium in life has two peaks.The one, budding to blooming, the nitrogen of Xi Shouing, phosphorus, potassium account for 32%, 34% and 33% of the time of infertility respectively during this period of time; The 2nd, to bloom to containing bell, nitrogen, phosphorus, potassium that this stage absorbs account for 44%, 50% and 48% of the time of infertility respectively.This two periods after cotton emerges 50～100 days.70%～75% nitrogen discharged in this period in the controlled release fertilizer special for cotton prescription.Thermoplastic resin membrane wrapping urea in the prescription can prevent that then the cotton later stage from taking off fertilizer.
3. it is relatively more responsive to trace element zinc, boron to have added the special nutritive element cotton that needs of cotton.Zinc can promote the metabolism of cotton plant substance in vivo, and the promotion cotton early buddings, blooms and blow-of-cottons, flower rate before the raising frost, and the increase cotton ties the bell number and bell is heavy.Cotton must have boron to participate in pollen formation and fertilization process.Therefore when cotton seriously lacks zinc, boron deficiency, the mesophyll chlorosis, plant is short and small, and flower abscission, or flower bud and not spending have a strong impact on output.Controlled release fertilizer special for cotton has added zinc sulfate and borax specially.
3. effect of increasing production is good, and the high controlled release fertilizer special for cotton of utilization rate of fertilizer can significantly increase output of cotton, improves the particularly utilization ratio of nitrogenous fertilizer of fertilizer.Compare with executing the common chemical fertilizer of equivalent, use the controlled release fertilizer special for cotton output of cotton and improve 15%～28%, utilization rate of nitrogen fertilizer improves 11.3%～18.2%.Even rate of fertilizer application reduces under 20% situation, use the fertile output of cotton of controlled release and also improve 6.4%～8.5% than executing common fertilizer.
