红枣是内黄县农业生产的一大优势。全县现有枣树27.5万亩,450万株,其中结果树400万株,年产鲜枣1500—2000万公斤,产值800万元左右,产量、面积、产值均居全国产枣县的首位。近年来,由于生态环境的改变,导致枣树树形紊乱,病虫害严重,产量和品质逐年下降。为此,我们配合县内外有关部门组织协作攻关,总结出一套丰产管理综合技术措施。经小区试验示范,当年创单株产枣 Jujube is a major advantage of agricultural production in Neihuang County. The existing jujube 27.5 million mu, 4.5 million, of which 4 million tree results, with an annual output of 15,000-2000 million kilograms of fresh dates, the output value of about 8000000 yuan, output, area, output value ranks first in the national jujube County . In recent years, due to the change of the ecological environment, jujube tree deformity, pests and diseases are serious, yield and quality declining year by year. To this end, we cooperate with relevant departments at home and abroad to organize collaborative research, summed up a comprehensive management of high yield technical measures. Demonstration by the district trial, then a strain of jujube
