种樱桃只开花不结果,是怎么回事?

  樱桃由于开花比较早,所以成熟期也比较早、樱桃的市场行情比较好,吸引了很多果农的种植,但由于果农技术掌握不够成熟、果树管理不到位,以及早春灾害性气候等因素的影响,经常容易出现果树开的花不少、结果到最后挂果率却很低的现象。

  


  避免樱桃树坐果低的举措

  一、提高花期的授粉能力

      1、合理搭配授粉树

  建园时最好配置与主栽品种授粉亲和力高、花粉量大、花期一致,且适应性强、
品质优的品种作为授粉树。栽植时,建议主栽品种与授粉品种按比例进行穿插栽植。


  2、果园放蜂促进授粉

  由于樱桃开花较早,建议在樱桃开花前1周把蜂箱放在园中,每亩可放80~ 100头,可以很好的促进授粉。

  3、人工辅助授粉

  樱桃花粉量大,果农可以在盛花期用鸡毛掸子在不同品种的花朵上来回滚动,持续3~5 天,通过人工辅助授粉来增强授粉效率,提高坐果率。

  二、做好果园低温晚霜等危害樱桃树开花期一般在每年的3月初到4月初,属于早春,气温不稳定,果树容易受到低温晚霜的危害。因此要提前做好防范措施。大家可可采用早春灌水的办法降低地温,或者在霜冻来临之前,给树上喷水,提高园内温度。


  三、喷施植物生长调节剂,提高坐果率花期和落花后,果农可以喷施1-2次40 mg/L~50
mg/L赤霉素,可明显提高樱桃的坐果率。在樱桃果实生长期喷PB0 250倍液,不仅可提高果实的坐果率,而且可促进果实着色,提高果实品质。


  四、加强花期前后的肥水管理

  樱桃树谢花后到果实成熟前是需水临界期,建议果农在樱桃开花前灌1次水,主要用来改善果园内土壤湿度,可促进坐果,避免因干旱引起落花落果。另外,建议果农在盛花期喷施0.
3 %硼砂+0. 3 %尿素溶液,可以提高坐果,改善果实品质。此外,还要对果树进行科学修剪,及时疏花疏果,合理负载,增强树势,多留壮枝结果。

总的来说,授粉和施肥都是必不可少的。

很有可能是植物养分过足导致的。在植物开花期间,适量的补充氮肥和钾肥肥料的浓度不宜过高。也有可能是温度长时间的比较高。应该适量的补充水分,降低温度。

回答3:

1、栽种方式不正确。
2、气候不适宜。 要看当地是否适宜种植樱桃。樱桃有中国樱桃和欧洲甜樱桃之分,中国樱桃适应性广,而欧洲甜樱桃适应性相对较窄,对气候条件要求较严格,要求光照充足、降水较少、昼夜温差大、冬季低温量充足,否则成花困难,或花芽分化发育不良。
3、树势徒长。营养浪费花芽未发育不成熟,也会不结果。
4、开花的时候经常遇到阴雨天,没有授粉的昆虫。
5、结果的过程中部分果实被小鸟啄食。
6、土壤中缺乏磷元素。

回答4:

一是环境不适,它对环境要求较高,要根据所在地的气候环境进行栽种管理才行。
二是树势徒长,要及时修剪,让养分更集中些,促使更好的开花结果。
