通过不同栽培密度、不同畦高的复因子试验的观察,表明地膜覆盖栽培甜瓜,可使出苗时间提前4—5天。在生长发育期间株高平均提高2.65cm,株幅平均宽7.43cm,叶片数平均多1.66片,茎平均粗0.76mm。开花期叶片数增加15.93片,一次侧蔓瓜多结2.68个,并可提前在3次侧蔓上见瓜。 经对三因素复因子(2×2×2)方差分析表明,覆盖因素为产量效应的主导因素,对总产量的提高十分明显(P<0.01)。覆盖区可增产55.49％,每亩多收瓜919.59市斤,可得净收入146.92元左右。可以认为地膜覆盖栽培甜瓜,方法简便,基本免耕,是获得增产增收的有效途径。
The observation of complex factor test with different cultivation density and different height showed that mulching with melon-covered mulching could make emergence time 4-5 days earlier. During growth and development, the plant height increased by 2.65cm on average, the average breadth was 7.43cm, the average number of leaves was 1.66, and the average stem diameter was 0.76mm. The number of flowering leaves increased by 15.93 pieces, 2.68 pieces of melon knot once on the side, and can be seen on the 3rd side of the vine. The variance analysis of 3 × 2 × 2 factors showed that the coverage factor was the dominant factor of yield effect, and the total yield was obviously increased (P <0.01). Coverage area can increase 55.49%, 919.59 kg per acre more harvest jin, net income may be 146.92 yuan. Mulch can be considered mulching cultivation, the method is simple, basic no-tillage, is to obtain an effective way to increase production and income.
