近年来,金山县蔬菜生产发展很快,拥有市属常年菜地10689亩。茄子是春季生产的大宗蔬菜作物,由于产品集中在春、夏季投放市场,受市场制约,经济效益不高。1994年,县菜办经过市插调查,提出了茄子反季节栽培的设想,并成立了课题组,选择了基础条件较好的新农镇蔬菜基地场开始了茄子反季节栽培试验,试种6只大棚,于8月7日和20日分二批播种育苗,9月26日起定植,当年11月19日开始采收果实。元旦春节向市场供应242.75kg鲜嫩茄子,丰富了节日市场,受到了消费者的欢迎。现已推广反季节茄子289棚,占全县大棚栽培茄子的63.8%,经济效益十分显著。据统计,反季栽培茄子平均亩产值5505.99元,比常规大棚栽培茄子亩产值增加2368.49元。主要栽培技术如下: 一、大棚保暖增温 茄子是喜温蔬菜,大棚保温是成败的技术关键。茄子生育所需的适温,苗期白天为25℃左右,夜间15—18℃,开花结果期白天为25—30℃,夜间20℃左右,按照这些要求,大棚按畦加套小环棚,定植活棵期在大棚薄膜上再覆盖一层草帘,恢复生长后除去草帘。以增加棚内光照。12月中
In recent years, Jinshan County vegetable production has developed rapidly, with a perennial vegetable 10689 acres. Eggplant is a large-scale vegetable crop that is produced in spring. As the products are concentrated on the market in spring and summer, the market is restricted and the economic benefits are not high. In 1994, the County Office of food through the market survey, put forward the idea of counter-season cultivation of eggplant, and set up a research group, select the basic conditions of good new town vegetable base field started the eggplant off-season cultivation test, test 6 Only a greenhouse, on August 7 and 20 divided into two batches of seedlings planted September 26 from planting, then November 19 that year began harvesting fruits. New Year’s Day Spring Market to supply 242.75kg of fresh eggplant, enrich the holiday market, has been welcomed by consumers. Has been promoting anti-season eggplant shed 289, accounting for 63.8% of the county greenhouse cultivation of eggplant, the economic efficiency is very significant. According to statistics, the average yield per mu of eggplant cultivated in the counter-season is 5505.99 yuan, an increase of 2368.49 yuan more than that of the normal cultivation of eggplant per mu. The main cultivation techniques are as follows: First, the greenhouse warming warming Eggplant is a warm vegetable, greenhouse insulation is the key to success or failure. Suitable temperature for eggplant fertility, seedling daytime is about 25 ℃, night 15-18 ℃, flowering during the daytime of 25-30 ℃, at night about 20 ℃, according to these requirements, the greenhouse by 畦 plus sets of small shed, Planting live in the greenhouse film and then covered with a layer of straw curtain, grass straw removed after the restoration of growth. To increase the shed light. Mid-December
