我区早春黄瓜主要是保护地一塑料大棚栽培。在大棚面积有限的条件下,如何早熟丰产就成了春季大棚黄瓜栽培中最重要的问题,而苗期喷用乙烯利便可达到这一目的,并且这一技术容易掌握,成本低,效果明显。乙烯利对黄瓜主要起促进雌花分化、抑制雄花分化的作用,同时降低了第一雌花节位。在苗期喷用乙烯利可以使1—20节位的雌花数增加2—3倍,由此结瓜数大幅度增加,总产量增加30%以上;第一雌花节位可降到第三节,早期产量可提高50%左右;同时乙烯利喷用得当可促使幼苗健壮,表现为节间短、茎粗、根系发达、叶片肥厚,
Early spring cucumber in my area is mainly protected by a plastic greenhouse cultivation. Under the conditions of a limited area of a greenhouse, how early maturity high yield becomes the most important issue in cucumber cultivation in the spring greenhouse, ethephon sprayed at the seedling stage can achieve this goal, and this technology is easy to grasp, with low cost and obvious effect. Ethephon on cucumber mainly promote female flower differentiation, inhibition of male flower differentiation, while reducing the first female flower node. Spraying ethephon at the seedling stage can increase the number of female flowers of 1-20 nodes 2-3 times, thus the number of cucumbers increased significantly and the total yield increased by more than 30%. The first female flower node could be reduced to the third node , Early yield can be increased by about 50%; the same time ethephon spray can promote seedling robust, manifested as internodes short, thick stems, roots developed, leaf hypertrophy,
