example 1

[0045] Example 1: Test of growing willow trees in a greenhouse. Two layers of nutrition and water retention bags, the inner bag 1 has a diameter of 20cm and a height of 49cm, the outer bag 2 has a diameter of 36cm and a height of 54cm, and the paper quality is 80g / m 2 , between inner and outer bags 1 and 2, 425g of water-absorbing resin / bags are applied. The control is pure calcareous sandy soil, where willow trees are planted directly. The inner layer bag 1 of the nutritional water retention bag is filled with peat, calcareous sand, 310g of slow-release nutrients and 0.5mg of plant growth regulator 5. Willows were planted in pots with a bottom diameter of 50 cm. After planting, both the control and nutrient water retention bags were watered with 5 kg. Avoid rainwater during management. Observation after 80 days, compared with withered and dead, the willow plant in the nutrient water retention bag grows vigorously, and the bag is opened to watch, and many new roots grow out...

example 2

[0046] Example 2: Experiment of planting boxwood in greenhouse. Three layers of nutrition and water retention bags, the inner bag 1 is 20cm in diameter and 49cm in height, the middle bag 6 and the outer bag 2 are 36cm in diameter and 54cm in height, and the paper quality is 100g / m 2 , 50g / only water-absorbing resin 4 is coated between middle and inner bag 6,1. 38g of slow-release nutrition is applied between the outer bag 2 and the middle bag 6, and 0.5mg of the plant growth regulator 5 is placed in the inner bag 1. The control is pure calcareous sandy soil, where trees are planted directly. The inner layer bag 1 of the nutrient water retention bag is filled with calcareous sand and peat. The control died soon, but the nutrient water-retaining bag Buxus survived for more than 80 days without adding water and grew many new roots.

example 3

[0047] Example 3: Greenhouse planting Caragana test. Control, two-layer and three-layer nutritional water retention bags were treated. The inner bag 1 of the two-layer nutrient water retention bag has a diameter of 18cm and a height of 38cm. The inner layer bag 1 of the three-layer nutrient water retention bag has a diameter of 18 cm and a height of 38 cm. Contrast is that pure calcareous sandy soil is directly planted trees, and the calcareous sandy soil and peat ratio of packing into the nutrient water retention bag inner layer bag 1 are 1:1, 1:2, 2:1 respectively. Planting and management methods are the same as examples 1 and 2. Observation after 70 days shows that the control leaves are withered and yellow, falling off, and have no new roots, while the caragana plants in the nutrient water retention bag grow well, with lush green branches and more new roots.

Abstract

The invention provides an environmental paper bag applied to planting economic fruit trees and afforestation in drought and quasi-drought regions. It is characterized by that paper quality bags are adopted; water sucking resin is between internal bag and external bag; slow releasing nutrition 3 is between internal bag and the outside layer of multi-layer bag; plant growth regulator is within internal bag.

Description

technical field [0001] The invention belongs to the fields of agriculture, forestry and economic plant planting, in particular to a water-saving paper bag for seedling nutrition and water retention. Background technique [0002] There are 38 million hectares of desertified land on the earth 2 , of which Asia accounted for 32.5%, Africa accounted for 27.9%, Australia accounted for 16.5%, and other continents accounted for 23..1%. In recent years, about 6 million hm 2 The land is desertified. The area of ​​desertification in my country has reached 2.622 million hm 2 , accounting for 27.3% of the country's land area, and expanding about 2460km every year 2 . Since the founding of the People's Republic of China, my country's greening and sand control work has made great achievements, but due to land reclamation, overgrazing, and indiscriminate land reclamation, land desertification is still very common, and the speed of sand control cannot keep up with the speed of desertif...
