- W2390664254 abstract "A study of the effect of different film and different covering methods on the yield of potato was made. The result showed that for the dryland film-mulching potato, the effect of the black film whole-mulching furrow sowing in autumn on drought resistance and seedling protection was best and the rate of emergence was the highest reaching 98%. Compared with the control, with the black film whole-mulching in autumn the moisture content of 0~60 cm soil during the period of emergence was 7.4% higher, the utilization rate of rainfall was 9.8% higher and the water production efficiency was 18.0 kg/(mm·hm2)higher. It was beneficial to the emergence of the potato and the upgrading of the drought resistance capability. As for different film-mulching methods, the sequence of their effects on the drought resistance, water-saving and yield increasing was the whole-mulching in autumn the whole-mulching in early spring half-mulching in autumn whole-mulching during the date of seedinghalf-mulching in early springhalf-mulching during the date of seedingopen field. The yield with the black film whole-mulching in autumn was the highest, 17 409.96 kg/hm2, 43.63% higher compared with that of the control. The yield with the white film half-mulching during the date of seeding was lowest, 13 394.1 kg/hm2,10.5% higher than that of the control. The product value and net income of the potato covered with black film was higher significantly than those of the potato covered white film and those with whole-mulching was higher than those with half-mulching. The net incomes of the black film whole-mulching in autumn and the white film whole-mulching in autumn were 15 893.29 yuan/hm2and 12 249.17 yuan/hm2higher than that of the open field and the effects on yield and income increasing were significant. It is suggested that black film should be used in film-mulching cultivation of potato to promote yield increasing and income increasing." @default.
