一、增施肥水,提高树体营养水平 枣树在一年的生长、结果中消耗了大量的养分,需要及时补充,枣子收获后施基肥就是补充养分的主要措施。基肥最好是秋施,也可冬施。即在枣树落叶后,土壤封冻前施。若年前没有施,初春发芽前也应补施。 施肥有撒施和沟施方法两种。撒施是把圈肥均匀撒于树冠下,然后翻入土中。沟施分为放射状沟施和井形沟施。幼树应采用放射状沟施,做法是在距树干20厘米到树冠外围,挖6—8条宽20—40厘米、深10—20厘米、内浅外深、内窄外宽的放射状沟,将圈肥施入并覆土。结果树采用井字形沟施,在树冠下顺行挖宽30厘米、深15—20厘米的沟,沟距30厘米,施入圈肥,覆土整平。下年施肥沟从垂直树行的方向开挖,与前一年施肥沟构成井字形,以增加施肥面,提高施肥效果。枣树根系受伤后不易恢复,开沟时应注意保护直径0.5厘米以上的粗根,不要断伤。
First, increasing fertilizers to improve the nutritional level of trees Jujube growth in the year, the results consume a lot of nutrients, the need for timely replenishment, jujube post-harvest base fertilizer is the main measure to supplement nutrients. Basal fertilizer is best autumn, but also winter Shi. That jujube leaves, the soil before freezing applied. If no years ago Shi, early spring should be supplemented before sprouting. There are two methods of spreading and applying fertilizer. Sassafras is evenly lapped in the canopy under the crown, and then turned into the soil. Ditch facilities divided into radial ditch and well ditch facilities. Saplings should be radial ditch facilities, approach is 20 cm away from the trunk to the crown periphery, dug 6-8 20-40 cm wide, 10-20 cm deep, shallow inside and outside the narrow, narrow radial outer ditch will be Circle fertilizer applied and casing. The results of the tree using well-shaped ditch facilities, along the ditch canopies widening 30 cm, 15-20 cm deep trench, ditch 30 cm, applied to the loop fertilizer, covering leveling. Next year fertilization ditch from the direction of the vertical tree row excavation, fertilization ditch with the previous year to form a glyph, in order to increase the fertilization of noodles and improve fertilization effect. Jujube root injury is not easy to recover after root canal, ditch should pay attention to protect the root diameter of 0.5 cm or more, not broken.
