俗语说“苗好五成收”。秧苗质量的好坏,对蔬菜生产影响很大。夏季育苗时,由于受高温、暴雨、强光、病虫害高发等众多不利因素的影响,培育壮苗极为不易,而秋菜、秋延迟菜及部分越冬菜,又均需在夏季育苗。因此,如何克服夏季不利因素,培育高质量的秧苗,是蔬菜生产者所必须掌握的技术。 一、苗床准备 （一）苗床选择 夏季育苗床,应选择地势平坦高燥,排水良好,背阴通风的田块。 （二）营养土配制 选用肥沃且未种过与所育蔬菜同科作物的田土,将充分发酵腐熟的有机肥过筛后,按土肥6比4的比例混合均匀。然后,在每1000kg营养土中掺入50％托布津或多菌灵80g,2.5％敌百虫 60g,以杀灭病虫源。最后,将配制好的营养土装入塑料钵或纸钵中。 （三）苗床制作 夏季育苗最好采用高畦,畦高一般为5-10cm,宽约1.0m,畦面要平整。做好畦后,将塑料钵或纸钵排于畦上,钵与钵之间用细沙填实。最后,于苗床四周挖好排水沟。
As the saying goes, “Miao good five percent income.” The quality of the seedlings, a great impact on the production of vegetables. Summer nursery, due to the high temperature, rain, glare, pests and diseases and many other adverse factors, nurturing strong seedlings is not easy, and autumn vegetables, late autumn vegetables and part of the winter vegetables, but also need nursery in the summer. Therefore, how to overcome the adverse factors in summer and cultivate high-quality seedlings is a technology that vegetable producers must master. First, the seedbed preparation (a) seedbed selection Summer nursery bed, flat terrain should be selected high dry, well drained, shady ventilation field. (B) the preparation of nutritious soil fertile and not planted with the vegetables of the same crop fields, will be fully fermented decomposed organic fertilizer sieved, according to the ratio of 6 to 4 soil fertilizer mixed evenly. Then, in each 1000kg nutrient soil mixed with 50% Topaz or carbendazim 80g, 2.5% trichlorfon 60g, to kill the source of pests. Finally, the prepared nutrition soil into the plastic bowl or pot. (C) seedbed production Summer nursery is best to use Gao Cheng, Gao Gao is generally 5-10cm, width 1.0m, noodles to be smooth. After doing a good job, put the plastic bowl or paper bowl in the bowl, bowl and bowl filled with fine sand. Finally, dredge ditches around the seedbed.
