Embodiment 1

[0050] This example takes Eupatoria adenophorum as an example to prepare special bag-controlled slow-release fertilizer for mango.

[0051] The above-ground plants of Eupatorium adenophorum were collected on the side of the road in Miyi County, Panzhihua City on June 12, 2013. According to the stem color of the above-ground plants of Eupatorium adenophorum, 10 tons of purple stem raw materials were obtained, and 10 tons of non-purple stems were obtained. 40 tons of stalk raw materials.

[0052] 10 tons of purple stalk raw materials are crushed into small sections of 3-5 cm, then placed in a refiner, and 2-3% by weight of biological refining aids are added to grind them into a paste. Then add chitosan and pasty liquid with a weight ratio of 15-30%, place in a mold and press to form the biomass bag surface. Paste the sides of the biomass bag surface and the transparent and degradable biodegradable film bag surface, and sew them into a controlled-release bag with a width of 10 c...

Embodiment 2

[0058] In order to test the fertilizer effect of the bagged controlled-release fertilizer in Example 1, the present embodiment has carried out the fertilization experiment of the 'Haydun' mango adult tree. The specific method is: after picking fruit in the autumn of 2013, fertilize the mango trees in the mango orchard. Apply 10 bags of bagged slow-release fertilizer in embodiment 1, make fertilization rate reach total nitrogen 180kg / hm 2 ,P 2 o 5 150kg / hm 2 、K 2 O160kg / hm 2 . Simultaneously, apply the same nutrients as in Example 1 directly, put them into controlled-release bags prepared by film bags with micropores on the top and bottom, and use no fertilization as a blank control.

[0059] By 2014, the experimental results are as shown in Table 1. As can be seen from the table, when the controlled-release fertilizer nutrient formulation of the present invention is adopted without bagging, the yield per mu is 1.14 times that of no fertilization. When the controlled-rele...

Embodiment 3

[0063] In order to test the controlled-release effect of the bagged controlled-release fertilizer in Example 1, a watering experiment of the bagged controlled-release fertilizer was carried out in this example. In the experiment, two types of controlled-release bags were set, namely: a) the upper and lower surfaces of the biomass bag with micropores and permeable water of the present invention were used; biodegradable film. The two types of bagged fertilizers were placed in 300ml of water for treatment, and the volume of water lost at the bottom of the bag and the nitrogen content in the lost water were collected respectively.

[0064] The experimental results of this embodiment are shown in Table 2. It can be seen from the table that when the lower bag surface of the controlled-release bag is an impermeable film, after watering treatment, a funnel-shaped waterproof structure can be formed, so that the moisture in the running water is only up and down. Both adopt water-permea...

Abstract

The invention discloses a method for preparing a bagged controlled release fertilizer from Ageratina adenophora. The method comprises the following steps: (a) dividing plants of Ageratina adenophora on the ground into a purple stalk raw material and a non-purple stalk raw material; (b) carbonizing the non-purple stalk raw material, so as to prepare biomass charcoal; (c) preparing a permeable biomass bag surface from the purple stalk raw material; (d) preparing a controlled release bag from the biomass bag surface and a transparent and non-permeable biodegradable film; and (e) mixing the biomass charcoal, grass charcoal composted by virtue of beneficial microorganism fermentation and inorganic nutrients in a certain proportion, and sealing the mixture in the controlled release bag, so as to obtain the bagged controlled release fertilizer. According to the bagged controlled release fertilizer, the nutrients can be synchronously released according to the requirements of crops to the nutrients, so that the loss of the leached nutrients after raining or watering operation can be effectively prevented; compared with an existing controlled release fertilizer, the utilization rate of the nutrients is improved by 5%-16%, and the economization and the environmental protection are well achieved. According to the preparation method, Ageratina adenophora which is an invasive plant is turned into wealth, so that huge ecological and economic benefits are achieved; the preparation method is worthy of being popularized and applied.

Description

technical field [0001] The invention belongs to the field of forestry biotechnology, and in particular relates to a method for preparing bagged controlled-release fertilizer by using Eupatoria adenophorum and the application of Eupatoria adenophorum. Background technique [0002] After the traditional fertilizer is applied, the fertilizer effect is short, and the absorption capacity of the crop is limited. Therefore, it is difficult for the nutrient to be completely absorbed by the crop within a short period of time after fertilization. Afterwards, due to reasons such as watering, rain showering, high temperature evaporation, and soil fixation, huge losses are caused. Waste, fertilizer nutrient utilization rate is generally about 30%. This phenomenon will not only lead to an increase in the amount of fertilizer used and increase the cost of agricultural production, but also seriously endanger the agricultural ecological environment and food safety. [0003] In recent years,...
