近年来,西宁市郊区塑料大棚发展迅速。但这些蔬菜播种育苗方法仍是采用温室手工操作,劳动强度大,占用人工多,育苗成本高,风险性较大。由于劳力及温室的限制,有时不得不采用育短令小苗甚至直播方法进行栽培,致使大棚栽培的早熟增产效果不能充分发挥。由于气候变化和缺乏经验,有时给育苗带来较大的威胁和损失。为了改变这种小农经济的育苗方式,尽快把蔬菜生产搞上去,逐步走向蔬菜工厂化。今年,我们在学习上海经验的基础上,对蔬菜工厂化育苗(也称快速育苗)进行了试验。实践证明:
In recent years, suburban plastic greenhouse in Xining has developed rapidly. However, these vegetable sowing and nursery methods are still used in the greenhouse by hand, labor-intensive, occupy more labor, nursery high cost, greater risk. Due to labor and greenhouse restrictions, and sometimes have to adopt the law of seedlings and even short-sowing live cultivation, resulting in greenhouse cultivation of early maturing stimulation effect can not give full play. Due to climate change and lack of experience, sometimes give nursery bring greater threat and loss. In order to change the mode of raising seedlings in this small-scale peasant economy, the vegetable production should be promoted as soon as possible and the vegetable factory should be gradually moved toward. This year, on the basis of our previous experience in Shanghai, we conducted experiments on vegetable seedling breeding (also known as rapid seedling raising). Practice shows that:
