Plastic film mulching on cotton yield

Transplanting cotton) are not coated with the conventional cultivation (conventional transplanting cotton) to compare experimental observation + film obtained transplanting cotton lint yield 1726Skg/hm, the control area than conventional transplanting cotton yield 3098 results. Transplanting cotton while warming film by moisture and soil characteristics and physiological reproductive machine looking cotton were measured and analyzed, clear plastic film covering the effect on cotton yield and mechanism of priming. 1 to tendon effects of mulch on soil temperature, soil environment. After the cotton seedling transplanting, mulching cotton soil temperature is always at a high state, the determination of film transplanting cotton s late May to late June at an average temperature of 26 5cm soil layer. L ℃, higher than the control conventional cotton transplanting 3.7 3 Degree of soil indignant; film to removing film after transplanting cotton before transplanting (July relatively stable state in early Tanzania. 0.5 ~ 5cm of soil water Gu transplanting cotton cloudy film 244. Transplanting than conventional cotton were high-53, Sunny 24.6. transplanting than conventional cotton were high 6.5, s ~ lOcm soil moisture cloudy conventional transplanting cotton than the control, 1.2, sunny conventional transplanting cotton than the control is 1,[link widoczny dla zalogowanych], but also proved by measuring the rainfall pair, cotton coated film after transplanting buffer soil water infiltration, soil moisture and keep the membrane is relatively stable, to avoid the effects of waterlogging. Soil bulk density: mulching cotton soil water and weather conditions as well, the soil physical and chemical properties have improved. mulching 3O days after the determination of soil bulk density, film transplanting transplanting cotton conventional cotton than the control low 1905-12 average income of a o5 gather in harvest 62. S; f ∈ .o.O9g/cm '. 2 film on the cotton plant physiological effects of reproductive function of a root insertion force enhancement, plastic love the cover of its warming effect,[link widoczny dla zalogowanych], the cotton plant root activity strong, 3 days after transplanting the origin of new roots, compared with the control routine transplant cotton as early as 4 to 5 days, thus shortening the Dunmiao period. labor to John foliage test. film shoots transplanted cotton plants new transplanting time than conventional cotton were 10 days earlier, is 5 to 7 days in advance Jian second birth process significantly earlier. Ring the bell and high strength. hairpin Amnesty film are Kan cotton. anthesis, respectively on June 5 and July 5, transplanted conventional cotton than the control as early as 5 days and 6 days respectively. at increasing the wrong o.3 Ten or more conventional than the control bees transplanted cotton of 5 days earlier,[link widoczny dla zalogowanych], the peak for the o.5 October / day plant, transplanted conventional cotton than the control high-to14 October / day plant cotton .3 mulching piles into the population structure provide coordination and reasonable Cotton after transplanting, mulching practice. Cotton steady rapid growth above ground,[link widoczny dla zalogowanych], fourth leaf width to maintain 12 ~ 13cm. transplanting conventional cotton than the control step 1 ~ 2cm. population growth, but only to the strong, not weak atlas. from the body of trend Look, cotton skirts Film Festival branches shift the ratio of 541l, the ratio of 3.55:1 leaf bell, bell branch ratio l_81I, the control section of conventional technology transfer indigo cotton This is 5.38tI, leaf ratio of 4.97:1 bell , wrong rod ratio I.33,[link widoczny dla zalogowanych], 1. Film Festival branches transplanted cotton boll and zinc were higher than in control than the conventional column transplanting cotton, and reasonable. is conducive to optimizing the quality of groups of cotton, has played a coordinating reasonable effect. In summary, the film transplanting cotton soil conditions are improved and enhanced vitality of cotton newspapers to promote the cotton plant growth and impaired shoot 1 minute early-onset, extending the effective boll flowering stage, increased light effect Ten groups to regulate the cotton leaves, investment, saving, bell structure, so that tends to coordinate to achieve the purpose of gain increase. ● iv Shan snail
