苹果园采用“四棵苗捆绑”法建园可以达到3年始果,4年回收当年投资,5年丰产的目的,其技术要点如下: 在10—11月份选用生长健壮的两年生苹果苗,其高度为100—110厘米,干粗0.8～1.0厘米,做为建园苗。设定栽植密度为2米×4米,每667平方米需苗量为83×4=332棵。栽植前,先把苗木4棵为一组用稻草绳紧紧的缠绕在一起(缠绕前先把树苗干部要接触的部分用刀刮一下露出皮层),缠绕高度为40—45厘米,然后对根修剪,位置处 Apple orchard using the “four seedlings tied” Law Park can achieve the initial fruit of 3 years, 4 years to recover the investment that year, 5 years of high yield purposes, the technical points are as follows: 10-11 months in the selection of robust two-year-old apple seedlings, its Height of 100-110 cm, dry coarse 0.8 to 1.0 cm, as built garden seedlings. Set planting density of 2 m × 4 m, 667 m 2 for each seedling volume is 83 × 4 = 332 trees. Before planting, first seedlings 4 as a group closely tied together with a straw rope (before winding the stems of saplings to contact the part of the knife with a knife to reveal the cortex), the winding height of 40-45 cm, and then the root Trim, location
