茭瓜又名西葫芦.利用日光温室栽培茭瓜在我县已获成功,并取得了较高的产量,每亩产量可超过5000kg.一、培育壮苗 茭瓜壮苗的标准是苗龄30—35天,3—4片叶,高10cm左右,茎粗0.4—0.5cm,叶色浓绿,叶柄、叶片长度相近.温室栽培应选蔓短叶小,株型紧凑、不发生侧蔓、耐低温、弱光的品种.如阿尔及利亚茭瓜、花叶茭瓜、张选一号、早青等.按茬次适期播种,冬春茬茭瓜多在10月上中旬播种育苗,春茬茭瓜在12月下旬至1月上旬播种育苗.先用清水选种,用55℃温水浸泡15分钟,再用20—30℃水浸泡4小时,槎去粘液,晾干种皮,用湿纱布包好,置于25一30℃处催芽,刚露芽时即可播种.播前浇足底水,割坨的在水渗后按10×10cm切块,每块(袋)中央播1粒种子.上盖2cm营养土.出苗前保持高温(25—30℃),出苗后至真叶展开时,适当降温,白天20—25℃,夜间18-20℃.苗期干时晴天上午浇小水,浇水后放风,一般不施肥.二、定植与管理 深翻土地.每亩撒施有机肥5000kg,磷酸二铵40kg.按小行距50cm,大行距70cm开沟,沟中施有机肥每亩2000kg.筑成双峰高垄,盖上地膜.冬春茬茭瓜于11月中下旬按60cm株距定植,每亩1850株左右.在垄中央把地膜割成十字口,用小铲挖定植穴,把亩坨(袋)栽入穴中,低于垄
茭 melon, also known as zucchini. The use of solar greenhouse cultivation 茭 melon in my county has been successful, and achieved higher yields per acre can be more than 5000kg. First, nurturing strong seedlings Eggplant strong seedling seedling age criteria is 30-35 days, 3-4 leaves, about 10cm high, stem diameter 0.4-0.5cm, dark green leaves, petiole, leaf length similar to the greenhouse should be selected short leaves short leaves, plant compact, lateral vineman, low temperature resistance, weak Light varieties, such as Algerian gourd, Mogan melon, Zhang election on the 1st, early green, etc. Crops by sowing the appropriate time, winter and spring 茭 melon and more sowing seedlings in mid-October, spring 茭 melon in late December to 1 Seeding early in the month .Seed first with water selection, soaked with 55 ℃ warm water for 15 minutes, then soaked in water 20-30 ℃ 4 hours, 槎 go mucus, dried seed coat, wrapped with wet gauze, placed in a 25 30 ℃ at germination, just when the bud can be planted sowing before sowing the foot of water, cutting lumps after water seepage by 10 × 10cm cut, each block (bag) broadcast a central seed. Cover 2cm nutrient soil. Pre-emergence to maintain high temperature (25-30 ℃), the emergence of true leaves to expand, the appropriate cooling, 20-25 ℃ during the day and night 18-20 ℃. Seedling dry sunny morning pouring small water, water after the wind, No fertilizer .Second, planting and management Deep turning land .Apple organic fertilizer per acre 5000kg, diammonium phosphate 40kg .According to small row spacing 50cm, large row spacing 70cm ditching, ditch organic fertilizer applied in the ditch 2000kg .Built into a double peak High ridge, covered with plastic film. Winter spring stubble melon in mid-to-late November by 60cm plantation spacing, per acre 1850. In the ridge of the central cut the film into a cross, with a small shovel dig planting hole, mu lumps (bags) Into the hole, lower than the ridge
