冬季在温室内为早春拱棚和春菜培育秧苗,常出现因地低而造成种子发芽困难或臭瘫,出苗参差不齐,幼苗欠壮,猝倒病、枯萎病发生严重等问题。黄瓜、西葫芦、茄子等喜温性菜秧寒根后成片枯死或毁种,既浪费种子和劳力,又会错过适时的定植期;早熟甘蓝播早了,结球期易先期抽苔,播迟了上市迟,严重影响投入产出效益。新绛县城关镇新关村段贵安、西曲村文小方,1988年秋设计出一种利用苗床下设地下烟道调地温,培育菜苗的温床。取材容易,不烧煤炭,操作简单,地温可升可降,幼苗整齐健壮。通过两年的实践,收到较好
Winter in the greenhouse for early spring arch shed and spring vegetables nurturing seedlings, often due to low ground caused by seed germination difficulties or paralysis, uneven emergence, seedlings are not strong, damping off disease, wilt disease serious problems. Cucumber, zucchini, eggplant and other warm vegetables after the cold root into pieces withered or destroyed species, both waste seeds and labor, but also miss the timely planting period; early maturity cabbage sowing, early bolting stage bolting, sowing Late listing late, seriously affecting the input-output benefits. Xin guancun xin guan cun xin guan cun guan guan, xi qu cun wu xiaofang, the autumn of 1988 to design a use of underground flue under the ground to adjust the temperature, nurturing vegetable hotbed. Drawn easily, do not burn coal, simple operation, ground temperature can rise or fall, neat and tidy seedlings. After two years of practice, received better
