近几年来,我省淮阴县为了调整种植业结构,发展“三高农业”,大力推广大棚“春提早”辣椒与水稻轮作栽培技术,取得了增粮、富民的效果。全县稻椒栽培面积由1993年的18.6亩,发展到1996年的5000亩,四年累计推广面积12816.6亩,增加产值6354.5万元。而且对改良土壤、抑制病虫草害有明显效果。“春提早”辣椒栽培的技术关键如下: 一、适期早播 培育壮苗 冷床育苗一般在10月5-10日播种,品种以大果早丰一号为主,每亩用种量50-75g,需用苗床8-10m~2每平方米施腐熟猪杂肥10-12.5kg,复合肥80g左右。播前温汤浸种,用毒饵防治地下害虫,杀菌剂处理营养土。播后盖地膜,搭棚覆农膜增温保湿。分苗时必须采用营养钵,营养土用熟菜园土与40％腐熟猪杂肥配制而成,每立方米加蔬菜专用肥或复合肥1.5kg及草木灰10kg,过筛拌匀,堆闷24小时后灌钵。幼苗二叶一心时分苗,分苗前一天浇透水,分苗时要做到轻起,轻运,轻栽。栽后及时浇定根水,然后闷棚增温促扎根。分苗大棚采用“二膜一帘”覆盖方式,要求冬季棚温能维持在8℃以上。分苗大棚要求南北向,棚宽6m左右,棚高约1.8m,长50-80m。大棚内分二个畦,每畦设小棚,跨度约2.4m,高0.8m,中间留走道,两侧放草帘。采用多功能膜。大棚膜厚度0.06-0.07mm,小棚膜厚0.03-0.04mm。这种膜成本低,增
In recent years, our province Huaiyin County in order to adjust the planting structure, the development of “three high agriculture”, vigorously promote the shed “Spring Early” pepper and rice rotation cultivation techniques, and achieved the effect of increasing grain, enriching the people. County pepper cultivation area from 18.6 acres in 1993, the development of 5,000 acres in 1996, four years, a total area of 12,816.6 acres of promotion, an increase of 63.545 million yuan output value. And to improve the soil, inhibit pests and diseases have a significant effect. Spring early “pepper cultivation techniques are as follows: First, the appropriate early sowing strong seedling cold bed nursery in October 5-10 on the general sowing, big fruit ZF No. 1, the amount of 50 acres per mu -75g, the need to use seedbed 8-10m ~ 2 per square meter Shi Fu Shi pig mixed fertilizer 10-12.5kg, 80g of compound fertilizer. Sowing warm before soaking soup, with bait control underground pests, fungicides nutrition soil treatment. After sowing film, scaffolding plastic sheeting warming warming. Seedlings must be used when the nutrition bowl, nutrition soil with cooked garden soil and 40% rotten pig miscellaneous fertilizer preparation, each cubic meter plus vegetable special fertilizer or compound fertilizer 1.5kg and ash 10kg, sieve and mix, pile boring 24 hours After the pot. Seedlings two leaves one heart and one minute when the seedlings, the day before the seedling watering, sub-seedlings to be light, light transport, light plant. Timely rooted after pouring root water, then bored greenhouse temperature increase root. Divide the greenhouse with ”two films a curtain" coverage, shed shed temperature in winter can be maintained at above 8 ℃. Divide the greenhouse requirements North-South, shed width 6m, shed height of about 1.8m, length 50-80m. Greenhouse divided into two 畦, each 畦 shed, span about 2.4m, 0.8m high, leaving the middle of the walkway, put grass curtains on both sides. Multi-functional film. Greenhouse film thickness 0.06-0.07mm, shed film thickness 0.03-0.04mm. This film is low cost, increase
