大棚栽培蔬菜幾種形式：茄瓜類蔬菜早熟栽培是大棚栽培應(yīng)用普遍的項目。露地栽培一般在3月下旬至4月中旬定植，5月上旬至7月收獲。大棚栽培可提前在1-3月定植，3月下旬至7月收獲。上市早、產(chǎn)量更高，開花結(jié)果期延長，經(jīng)濟(jì)效益明顯。另外還可根據(jù)市場需要，提早播種莧菜、木耳菜、空心菜等喜溫綠葉蔬菜，提早上市。

1、品種(組合)選擇：番茄早熟品種選用早豐、日本大紅×矮紅；中熟種選用浙雜5號、蘇抗4號、5號等，甜辣椒選用熟性早、抗病、豐產(chǎn)而且適銷對路的優(yōu)良品種。辣椒：雞爪×吉林F1、早豐1號；甜椒：加配3號；茄子：閩茄1號、屏東長茄；黃瓜：津春2號、3號等。

2、定植：定植前10天進(jìn)行扣膜蓋棚。每畝施入廄肥或腐熟垃圾肥3000公斤、人糞尿2000公斤、復(fù)合肥50公斤，開深溝施或全層施，翻人土中。番茄，一個大棚整4條畦，畦帶溝1.5米，采用雙行定植，行距75厘米，株距20-30厘米，每畝種植2500---3000株。辣椒畝植3000株。茄子株距40-50厘米，每畝栽2000"--2400株。黃瓜畝栽植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.

鍍鋅苗床工藝差異是：熱鍍鋅是將工件除油、酸洗、浸藥、烘干后浸入溶化的鋅液里必定時刻，提出來即可。冷鍍鋅也叫電鍍鋅，是使用電解設(shè)備將工件經(jīng)過除油、酸洗后放入成分為鋅鹽的溶液中，并銜接電解設(shè)備的負(fù)極；在工件的對面放置鋅板銜接在電解設(shè)備的正極，接通電源，使用電流從正極向負(fù)極的定向移動，就會在工件上堆積一層鋅。安平華耀生產(chǎn)的鍍鋅苗床均采用熱鍍工藝，防腐蝕功能也是電鍍鋅的幾十倍。

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.
