近几年来,种枣树的人越来越多,但产量普遍不高。原因是枣树开花多,座果率却很低。现介绍几种行之有效的让枣树多结枣的方法。一、合理追肥枣树开花前的4月下旬至5月上旬,每株追施尿素0.75—1公斤或人畜尿35～50公斤,以利于根系发育和枝条生长,增加花蕾密度,提高座果率。6月中下旬幼果发育期,每株施尿素1公斤左右,过磷酸钙2—2.5公斤,草木灰4—5公斤,以加速果实生长,减少第二次落果,为来年丰产打下基础。二、适时喷水每年5—6月是枣树开花盛期,但这时热风较多,很容易使柱头干枯,花粉丧失活力,出现焦
In recent years, more and more kinds of jujube trees, but the yield is generally not high. The reason is jujube flowering, fruit set rate is very low. Now introduced several effective jujube tree jujube method. First, a reasonable top dressing jujube flowering before late April to early May, each topdressing urea 0.75-1 kg or 35 to 50 kg of livestock and urine, in order to facilitate root growth and shoot growth, increase flower bud density and increase fruit set rate . In mid-to-late June young fruit development period, each plant applied about 1 kg of urea, calcium superphosphate 2-2.5 kg, 4-5 kg of ash, in order to accelerate the growth of fruits and reduce the second drop, the next year to lay a foundation for yield. Second, timely watering May-June each year is the jujube flowering period, but when more hot air, it is easy to make the stigma dry, pollen loss of vitality, appear coke
