果农在打药水过程中,多数用大铁桶兑药。但有很多弊病:一方面农药对铁桶有腐蚀作用,使铁桶严重生锈,不几年就会烂透;另一方面,铁桶对农药有降低药效作用,特别是对波尔多液更为明显。为了解决这些问题,向你介绍一种经济实用的塑料膜“药水坑”。在果园里,挖一个底深口圆的“锅底形”坑,坑边垒一圈15厘米左右的高岗。坑的大小根据用药水量而定,0.5立方米的坑就能装500公斤药水。长期使用的坑里面和边岗最好是用粘黄泥拍打结实,然后用一块完整无孔的塑料膜铺在坑上面,采用扣水稻秧苗厚塑料膜较好。坑 Fruit farmers in the process of playing syrup, the majority of large metal buckets. But there are many drawbacks: on the one hand, pesticides have a corrosive effect on the iron drum, causing serious rusting of the iron drum in a few years; on the other hand, the iron drum has the effect of reducing the pesticide effect, especially on Bordeaux Obvious. In order to solve these problems, introduce you to an economical and practical plastic film “medicine puddle.” In the orchard, dig a deep hole at the end of the “pot-shaped” pit, pit edge encircled 15 cm high Kong. The size of the pit according to the amount of medication may be, 0.5 cubic meters of pit can hold 500 kilograms of syrup. Long-term use of the pit inside and the edge of the gang is best patted with sticky yellow mud, and then use a complete non-porous plastic film shop in the pit above, using buckle rice seedlings thick plastic film better. pit
