Environmental-protection and energy-saving cultivating bag for apples and preparation method thereof

Abstract

The invention discloses an environmental-protection and energy-saving cultivating bag for apples and a preparation method thereof, belonging to the technical field of fruit tree planting. The cultivating bag for apples comprises, from outside to inside, an external paper layer, an intermediate layer and an inner paper layer. The external and inner paper layers of the cultivating bag are made of nano-cellulose paper which is safe and environmental protection material and has high transparency and high flexibility and is renewable and degradable; the prepared cultivating bag for apples has good water resistance performance, good ventilating performance and increases the level of appearance of apples and guarantees the taste and output of apples. When apples are ripe, the cultivating bags can be picked off along with apples and packaged directly and act as package paper for apples, which saves time and lowers cost and becomes an efficient safe and environmental protection measure; wasted fruit bags will not bring pollution or damage to fruits nor effect the health of orchard workers so as to lay a solid foundation for green fruits.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, relates to fruit tree bagging technology, in particular to an environment-friendly and energy-saving apple cultivation bag and a preparation method thereof. Background technique [0002] my country is a big fruit country, the orchard area accounts for about 21% of the world's total area, and the total fruit output accounts for about 14% of the world's total output. However, my country's fruit export volume is small and the price is low, which accounts for a relatively small proportion in the world. Although there has been a slight increase in recent years, the export volume of fruit is still less than 3% of the world's total output, and the price is 60-80% lower than that of the United States and Japan. The export of fruit products has been plagued by the development of my country's fruit industry. The main reason is that most of the fruit trees in our country grow on barren land, wh...

Problems solved by technology

But because this fruit-growing bag adopts the color of yellow on the outside and white on the inside, the inner and outer layers are all opaque, and its light transmittance decreases, so that the pears lack light during the growth process, and the sugar production is low. Insufficient effect, easy to form local discoloration, affect the appearance quality of pears, and poor water retention, resulting in low water content of pears, which in turn affects the taste

More importantly, in the prior art, the fruit bag must be removed after the fruit is ripe, resulting in high cultivation costs and slow harvesting, which affects the time the fruit goes on the market
