1992年笔者开始探索丝瓜大面积连片栽培技术,亩产由1500kg提高到3000-4000kg,1995年高产田块亩产达到5000kg,形成了一套行之有效的栽培措施。 一、良种壮苗 选择深受无锡市民欢迎的丝瓜良种坊前90—3肉丝瓜,该品种具有主蔓结果性能好,第一雌花节位5-6节,雌花节率70％以上,抗病毒病能力强等优点。3月15日前后大棚电热线育苗,种子需粒粒饱满,苗龄不超过40天,4月20日-25日定植。 二、重施基肥 丝瓜生育期长,而且连续结果,需要大量的基肥。第一次每亩撤施鸡、鸟、羊粪1000kg或浓人粪尿2500kg、25％复合肥25kg,外加过磷酸钙15kg、氯化钾5kg,做好垄后再在垄中开12-15cm深的沟,施第二次基肥,随即盖土整平并在土表喷除草通或都尔等除草剂,覆盖地膜。 三、密植搭架 采用高密度栽培法,株行距为18× 75cm,每垄种双行,两行间距 30cm,每亩栽 4000株。瓜地四边打桩,埋水泥柱或粗毛竹,用铁丝固定拉紧,筑成1.8m高的大平棚,棚顶用铁丝和草绳扣成 18cm × 15-30cm大小的网眼,每株瓜秧旁插竹梢1根,梢顶端用草绳连接棚顶,这样行与行,田块与田块之间连成一片,形成一个大平棚。 四、整枝打叶 丝瓜定植后2个月内,竹梢上主蔓所结的果实都是早期产量,此时应打掉所有侧蔓,确保主蔓开花、结果,并向棚顶延伸,其间要用稻草绑?
In 1992, the author began to explore the large area of loofah contiguous cultivation techniques, increased from 1500kg to 3000-4000kg per mu, high yield plots per mu in 1995 reached 5000kg, forming a set of effective cultivation measures. First, the seedling strong selection Popular Wuxi lotus seeds Square welcomed by the former 90-3 shredded loofah, the varieties have the main vine fruit performance is good, the first female flower node 5-6, the female flower node rate of 70% or more, antiviral Sickness and other advantages. March 15 greenhouse hotline nursery, seed to be full of particles, seedlings not more than 40 days, April 20 -25 days colonization. Second, re-Shigeru basis Long-term growth of sponge gourd, and continuous results, the need for a large number of base fertilizer. The first withdrawal of each mu of chicken, bird, sheep manure 1000kg or concentrated manure 2500kg, 25% compound fertilizer 25kg, plus superphosphate 15kg, potassium chloride 5kg, do ridge and then open in the ridge to open 12-15cm Deep ditch, Shi second base fertilizer, then cover the soil leveling and spray the weeds or ethers and other herbicides, covering the plastic film. Third, the close planting Racks using high-density cultivation method, the row spacing of 18 × 75cm, two rows of each ridge, two rows of spacing 30cm, planted 4000 per mu. Melon to the four sides of piling, buried cement column or rough bamboo, iron wire fixed tension, built into a 1.8m tall Odaiba, shed with wire and grass rope into a 18cm × 15-30cm size mesh, next to each melon seedlings Plug in a bamboo tip, tip the top with grass rope connected roof, so that line and line, between the plots and plots into one, forming a large flat shed. Four, pruning to fight loofah 2 months after colonization, the bamboo shoots on the main vine fruit are all early yield, this time should be destroyed all side vine, to ensure that the main vine flowering, the result, and extended to the roof, during which Tied to straw?
