Embodiment 1

[0028] A forest land application method of bag-controlled fertilizer, which is made of degradable plastics and made into a bag body with a length and width of 12×9cm, which is packed into a packaging bag of slow-release fertilizer with a weight of 125g, and the designed fertilization amount of each bag is one year , there are two rows of symmetrical holes on the bag; weeds are removed and plowed on the land where trees need to be planted;

[0029] When using the strip furrow method, excavate a furrow with a length, width and height of 1.5×0.3×0.3m at a distance of 35cm between the rows, and apply the base fertilizer and the bag-controlled fertilizer in the ditch at the same time, and apply the base fertilizer at the bottom of the ditch. Then place the bag-controlled fertilizer with the hole facing upwards, the bag-controlled fertilizer application depth is 15cm, use a layer of 3cm thick straw to cover and then cover the bag-controlled fertilizer with soil;

[0030] There are 1...

Embodiment 2

[0034] A forest land application method of bag-controlled fertilizer, which is made of kraft paper and made into a bag body with a length and width of 12×9cm, which is packed into a packaging bag of slow-release fertilizer with a weight of 125g, and the designed fertilization amount of each bag is one year. There are two rows of symmetrical holes on the bag; weeds are removed and plowed on the land where trees need to be planted;

[0035] When applying the radial ditch method, dig a radial ditch with a length, width, and height of 1.10×0.15×0.20m 30cm away from the trunk. For trees ≦15 years old, dig 4 radial ditches, and for trees ≧15 years old, 6 radial ditches. The position of the ditch is alternated every year, 2 / 5 of the radial ditch volume is within the crown projection, and 3 / 5 is outside the crown projection; when applying, the base fertilizer and the bag-controlled fertilizer are applied in the ditch at the same time, and the base fertilizer is applied at the bottom of...

Embodiment 3

[0040]A forest land application method of bag-controlled fertilizer, which is made of degradable plastic and made into a bag body with a length and width of 14×12 cm, and packed into a packaging bag with a weight of 140g of slow-release fertilizer, and the designed fertilization amount of each bag is one year , there are two rows of symmetrical holes on the bag; weeds are removed and plowed on the land where trees need to be planted;

[0041] When using the strip furrow method, excavate a trench with a length, width and height of 1.8×0.5×0.5m at a distance of 60cm between the rows, and apply the base fertilizer and bag-controlled fertilizer in the trench at the same time, and apply the base fertilizer at the bottom of the trench. Then put the bag-controlled fertilizer with the hole facing upwards, the bag-controlled fertilizer application depth is 20cm, use a layer of 5cm thick straw to cover and then cover the bag-controlled fertilizer with soil;

[0042] There are 14 symmetr...

Abstract

The invention discloses a method for applying bag-controlled fertilizer in forest land, and belongs to the field of tree planting. The method comprises the specific steps that degradable plastic or kraft paper is adopted as a material and made into packaging bags which comprise bag bodies with the length of 12-14 cm and the width of 9-11 cm and are loaded with the slow release fertilizer with theweight of 125-140 g, the fertilizer application amount of each bag is designed for one year, and each bag is provided with two rows of symmetrical holes; weeds are removed from the land where trees need to be planted, plowing and levelling are conducted, application is conducted by means of a strip-shaped ditch or radial ditch method, when the radial ditch method is adopted for application, 4-5 ditches are dug for each tree which grows for 15 years or shorter, 6-7 ditches are dug for each tree which grows for 15 years or longer, and the locations of the radial ditches are alternative every year; during application, base fertilizer and the bag-controlled fertilizer are simultaneously applied in the ditches, the base fertilizer is applied to the bottoms of the ditches, then the surface, withthe holes, of the bag-controlled fertilizer is placed upwards, the bag-controlled fertilizer is covered with a layer of straw with the thickness of 7-10 cm, and then earthing is conducted. The application method is high in fertilizer utilization rate, has no negative impact on the environment, and has good economic benefits.

Description

technical field [0001] The invention relates to the field of tree planting, in particular to a forest land application method of bag-controlled fertilizer. Background technique [0002] my country's fertilizer consumption accounts for about 20-30% of the world's total fertilizer consumption, ranking first in the world. The average seasonal utilization rate of chemical fertilizers in developed countries is 50-60%, and the average seasonal utilization rate of chemical fertilizers in my country is only 30-35%. . The loss and waste of a large number of nutrients not only bring huge economic losses to the society, but also cause serious environmental pollution. [0003] Traditional fertilizers include various compound fertilizers, compound fertilizers, single-element and multi-element fertilizers, etc. These quick-acting fertilizers, which are applied loosely, have a quick effect after use, but the fertilizer effect is short, and the crop absorption capacity is limited. It is di...
