梨树在生长发育过程中,需要各种元素,其中锌是需要的重要元素之一。梨树常常因缺锌而引起小叶病发生。应用硫酸锌喷洒叶面,如不与适量石灰混喷,则易发生药害,使梨树叶片变焦脱落,给生产带来损失。根据国外专利资料,环烷酸锌是有机锌肥,具有无毒、使用方便、乳化性好、分散性大、无副作用等优点,增产效果显著。针对我国梨区存在缺锌的实际问题,1983年开始应用国内研制生产的水溶性环烷酸锌乳剂,在河北省永年县刘汉果园以鸭梨为试材进行田间试验。 Pear tree growth and development process, you need a variety of elements, of which zinc is one of the important elements needed. Pear trees often cause lobular disease due to zinc deficiency. Application of zinc sulfate spray foliar, if not mixed with the right amount of lime spraying, then prone to injury, the pear leaves zoom off, bringing losses to production. According to the foreign patent data, zinc naphthenate is an organic zinc fertilizer, which has the advantages of non-toxicity, easy to use, good emulsifying property, large dispersibility and no side effect, and the yield enhancement effect is remarkable. In order to solve the practical problem of lack of zinc in pear district of our country, the water-soluble zinc naphthenate emulsion developed and developed in China was started in 1983 and field experiments were conducted in pear orchard in Liuhan Orchard, Yongnian County, Hebei Province.
