机插秧的成功与否,育秧是关键,秧苗素质及秧片质量的好坏,直接影响到产量及机插效率。我们经过试验研究,提出2种新的育秧作业方法,并研制出2个与之配套的器具划片刀和泥浆筛。此育秧方法于1988年9月通过宁波市科委鉴定,在这2年的实践中,表现具有秧苗素质好、成秧率高、秧片质量好,漏株率低、省工、省本等优点。现将2种育秧作业法介绍如下:一、泥浆土作床土、田间整块地膜作隔层、划片起秧作业法(一)播前准备 1.采用一般市售地膜,宽度为
Seedling transplanting success or failure, nursery seedling is the key, the quality of seedlings and seedling quality is good or bad, directly affect the yield and machine insertion efficiency. After the pilot study, we proposed two new methods of planting seedlings and developed two matching tools for dicing knives and mud sieves. This method of raising seedlings in September 1988 by the Ningbo Municipal Science and Technology Commission identified in these two years of practice, the performance of a good seedling quality, high seedling rate, good quality seedlings, missed the rate of low strains, labor, the province and so on advantage. Now 2 kinds of seedling farming methods are as follows: First, the mud soil as bed soil, the entire field of the field as a barrier film, sowing seedlings from the operation method (A) sowing preparation 1 using the general commercial film, width
