Independent mulching film device for blueberry planting

Abstract

The invention discloses an independent mulching film device for blueberry planting. The independent mulching film device comprises an annulus protective ring, an annulus sealing block and an annulus pressing block; the upper end face of the annulus protective ring is inwards provided with an annulus water flowing groove; a plurality of water leakage holes are formed in the annulus water flowing groove; the lower end surface of the annulus water flowing groove is provided with a plurality of hollow vertical rods; the hollow vertical rods communicate with the water leakage holes; the lower end of each hollow vertical rod is provided with an inverted conical head; the inner wall of the annulus protective ring is provided with an annulus stepped ring; the annulus stepped ring is provided witha plurality of inserting holes; the lower end of the annulus pressing block is provided with a plurality of inserting columns; the inserting columns are matched with the inserting holes; and the annulus sealing block is pressed into the annulus water flowing groove. The structure of the independent mulching film device is simple, the film coating requirements of single blueberry plants can be met,and overall film coating is not needed, so that the problem that weeds bred among the plants are positioned under a thin film and cannot be removed is avoided. In addition, more materials can be saved, and material application to blueberry roots can be more conveniently.

Description

technical field

[0001] The invention relates to the technical field of planting devices for blueberry seedlings, in particular to an independent plastic film device for planting blueberries. Background technique

[0002] Cold protection in winter is one of the important production techniques for growing blueberries in the open field. The degree of lignification of raspberry branches is relatively poor, and the root system is relatively shallow. When the cold protection measures are not used properly, the light ones will have sticking and flower bud freezing damage, which will affect the growth of the tree and the yield and quality of the fruit; in severe cases, it will lead to failure of harvest, and even the whole plant will freeze to death. . Therefore, the low temperature in winter has become the biggest obstacle to cultivating blueberries in the open field in cold northern regions, and it is particularly important to do a good job of overwintering and cold protection fo...
