(一)特点低垄作覆膜抗旱栽培技术是在地膜覆盖的基础上降低其垄体高度。长期以来,地膜花生的垄高一直保持在15厘米左右,低垄作地膜花生的垄高则降至8-10厘米,垄高的降低,使垄沟变浅,从而使低垄作花生既具有地膜花生的抗旱保墒特点,又具有地膜花生所不具备的突出优点:①低垄作便于在垄沟取土,即便于在播种行膜上压土带;②增加膜顶面占垄幅宽的比例,提高土地利用率及合理密植;③减少垄两侧的悬针滑针数,提高花生的结果率和商品性。
(A) Features Low-ridge film mulching drought cultivation techniques is to reduce the height of the ridge on the basis of plastic film mulching. For a long time, the ridge height of mulched peanut has been kept at about 15 centimeters. The ridge height of mulched peanut with low ridge is reduced to 8-10 cm. The ridge height is reduced and the furrow is shallow. Thus, Drought-resistant soil moisture characteristics, but also has the outstanding advantages of mulching film does not have: ① low ridge in the furrow for easy access to soil, even in the sowing row of film pressure zone; ② increase the proportion of the top of the film occupy a wide ridge, improve land use Rate and reasonably close planting; ③ reduce the number of hanging needles on both sides of the ridge to improve the rate of peanut and the commercial product.
