梨树座果率的高低对梨果的产量影响很大,采取以下措施可显著提高梨树的座果率。1.早施花肥。开春后梨树的萌芽、开花、枝梢及叶片的生长,要消耗树体内的大量养分,养分跟不上不仅影响枝叶的生长,而且会导致严重的落花落果,因而早施很重要。花肥宜在2月上中旬施用,每株梨卡对可用腐熟猪牛粪8～10公斤、火土灰4～5公斤、尿素200～300克,与细土拌匀后呈放射状开沟施下,施后立即覆土。树势强、基肥足、土质肥、花芽少的梨树,可免施或少施花肥。2.芽前喷肥。此次施肥于开春
Pear fruit rate on the yield of pear fruit great impact, take the following measures can significantly improve the fruit rate of pear. As early as fertilizer. Pear tree after the spring of budding, flowering, shoots and leaves of the growth, to consume a large amount of nutrients in the tree, nutrients can not keep up not only affect the growth of foliage, but also lead to serious drop flowers, and therefore early application is very important. Flower fertilizer should be applied in mid-February, each pear on the available decayed pig cow dung 8 to 10 kg, ash 4 to 5 kg, 200 to 300 g of urea, mixed with fine soil after the radial ditching facilities Immediately after application of soil cover. Strong tree, basal enough, soil fertility, flower buds less pear, can be applied or less fertilizer. Sprout before budding. The fertilization in the spring
