一、目的: 地膜覆盖栽培蔬菜,是一种新的栽培技术,经过两年来在我区的试验证明:它对提高地温、保水、保肥、保持土壤疏松、防止杂草等方面都有明显效果,增产作用也很明显,特别是前期产量,一般增产都在50％以上。为了更进一步摸索到适合于覆膜条件下的栽培方式,更有效地发挥地膜的增产效果,特对覆膜后栽培西红柿需要的苗龄作以试验。
First, the purpose: mulching cultivation of vegetables, is a new cultivation techniques, after two years of testing in our district has proved that: it has to improve the ground temperature, water, fertilizer, keep the soil loose and prevent weeds, etc. have a significant effect , The role of stimulation is also obvious, especially in the early production, the general increase in production are more than 50%. In order to further explore the cultivation methods suitable for the conditions of film mulching, more effective use of plastic film yield, specially for the cultivation of tomatoes after the filming the seedling age for testing.
