大棚栽培蔬菜几种形式：茄瓜类蔬菜早熟栽培是大棚栽培应用普遍的项目。露地栽培一般在3月下旬至4月中旬定植，5月上旬至7月收获。大棚栽培可提前在1-3月定植，3月下旬至7月收获。上市早、产量更高，开花结果期延长，经济效益明显。另外还可根据市场需要，提早播种苋菜、木耳菜、空心菜等喜温绿叶蔬菜，提早上市。

1、品种(组合)选择：番茄早熟品种选用早丰、日本大红×矮红；中熟种选用浙杂5号、苏抗4号、5号等，甜辣椒选用熟性早、抗病、丰产而且适销对路的优良品种。辣椒：鸡爪×吉林F1、早丰1号；甜椒：加配3号；茄子：闽茄1号、屏东长茄；黄瓜：津春2号、3号等。

2、定植：定植前10天进行扣膜盖棚。每亩施入厩肥或腐熟垃圾肥3000公斤、人粪尿2000公斤、复合肥50公斤，开深沟施或全层施，翻人土中。番茄，一个大棚整4条畦，畦带沟1.5米，采用双行定植，行距75厘米，株距20-30厘米，每亩种植2500---3000株。辣椒亩植3000株。茄子株距40-50厘米，每亩栽2000"--2400株。黄瓜亩栽植2000-2400株。

Several forms of greenhouse vegetable cultivation: early cultivation of eggplant and melon vegetables is a common project of greenhouse cultivation. Open field cultivation generally takes place from late March to mid-April and is harvested from early May to July. Greenhouses can be planted in advance from January to March and harvested from late March to July. Early listing, higher yield, longer flowering and fruiting period, obvious economic benefits. Still can need according to the market additionally, sow amaranth early, agaric, water spinach and so on like lukewarm green leaf vegetable, appear on the market early.

1. Selection of varieties (combinations) : Early maturing varieties of tomatoes were selected as Zaofeng, Japanese red × Dwarf red; The medium ripe seeds were selected zhezar No. 5, Sukang No. 4, No. 5, etc., while the sweet pepper was selected as a good variety with early ripening, disease resistance, high yield and marketable. Chili: Chicken feet × Jilin F1, Zafeng No. 1; Sweet pepper: with no. 3; Eggplant: Fujian eggplant No. 1, Pingdong long eggplant; Cucumber: Jinchun 2, 3, etc.

2. Colonization: Membrane cover was carried out 10 days before colonization. Each mu is applied with 3000 kilograms of barnyard manure or rotten garbage, 2000 kilograms of human dung and urine, 50 kilograms of compound fertilizer, and deep ditches or whole layers are applied to turn people into soil. Tomato is planted in 4 rows in a greenhouse with 1.5 meters of furrow and 75 centimeters of row spacing and 20-30 centimeters of plant spacing. 2,500-3,000 plants are planted per mu. Three thousand plants of pepper were planted in mu of land. Plant eggplant 40-50 cm apart, 2,000 "to 2,400 plants per mu. 2, 000-2, 400 cucumber plants were planted in Chinese mu.

镀锌苗床工艺差异是：热镀锌是将工件除油、酸洗、浸药、烘干后浸入溶化的锌液里必定时刻，提出来即可。冷镀锌也叫电镀锌，是使用电解设备将工件经过除油、酸洗后放入成分为锌盐的溶液中，并衔接电解设备的负极；在工件的对面放置锌板衔接在电解设备的正极，接通电源，使用电流从正极向负极的定向移动，就会在工件上堆积一层锌。安平华耀生产的镀锌苗床均采用热镀工艺，防腐蚀功能也是电镀锌的几十倍。

The technological difference of galvanized seedbed is: hot galvanizing is to remove oil, pickling, leaching, drying after immersing in the dissolved zinc solution must at any moment, can be taken out. Cold galvanizing, also known as electric galvanizing, is the use of electrolytic equipment after the workpiece is removed oil, pickling into the composition of zinc salt solution, and connected to the negative electrode of electrolytic equipment; On the opposite side of the workpiece, a zinc plate is placed to connect with the positive pole of the electrolysis equipment, and the power is switched on. A layer of zinc will be deposited on the workpiece by using the directional movement of current from the positive pole to the negative pole. Anping Huayao production of galvanized beds are hot plating process, anti-corrosion function is also dozens of times of electric galvanized.
