Problems solved by technology

[0003] In the traditional fertilization of crops, the method of base application and topdressing is generally used to ensure the fertilizer supply of crops at each stage. Although this method can solve the nutrient requirements of crops in different periods, in actual use, repeated topdressing leads to fertilizer The loss rate increases and the utilization rate decreases, which increases the cost of fertilization and is not conducive to the surrounding environment. In addition, repeated top dressing also increases labor costs, and consumes more manpower for manual work

Embodiment 1

[0035] The inventor used the slow-release quantitative fertilization device for the growth and fertilization of tobacco plants

[0036] After base fertilization in the tobacco field (that is, applying organic fertilizers, such as pig manure, corn cake fertilizer, etc.), the slow-release quantitative fertilization device is placed on the roots of the tobacco plants, and the ratio is one bag per tobacco plant, wherein each slow-release The amount of fertilizer contained in the quantitative fertilization device is 50g, mainly N fertilizer, P fertilizer, K fertilizer, etc., and the non-woven fabric is made of polypropylene with a thickness of 40g / m 2 , which contains Ca 2 CO 3 The proportion by weight is 20%.

[0037] After application, the slow-release quantitative fertilization device can be poured during the traditional three-time topdressing.

Embodiment 2

[0039] The inventor used the slow-release quantitative fertilization device for the growth and fertilization of strawberries

[0040] After the basic application of strawberry field (i.e., the application of organic fertilizers, such as pig manure, corn cake fertilizer, etc.), the slow-release quantitative fertilization device is placed on the roots of strawberry seedlings, and the ratio is to put one bag for every four strawberries. The amount of fertilizer contained in the release quantitative fertilization device is 50g, mainly N fertilizer, P fertilizer, K fertilizer, etc., and the non-woven fabric is made of polypropylene with a thickness of 30g / m 2 , which contains Ca 2 CO 3 The proportion by weight is 15%.

[0041] After application, during the period of topdressing, the slow-release quantitative fertilization device can be watered.

Abstract

The invention provides a slow-release quantitative fertilization device which comprises a bag body and a fertilizer, wherein the bag body comprises a top bottom in contact with the ground and an opposite top surface; the bag body is made of a non-woven material. By virtue of the non-woven material, a fertilizer can be gradually released in the use process; above all, due to the biodegradable characteristic of non-woven, the ability of releasing the fertilizer is gradually strengthened along with growth of a plant; the slow-release quantitative fertilization device is suitable for nutrient supply for a crop in a later period, the fertilizer can be continuously supplied within relatively long time (the time is set to be consistent with that of growth of the crop in general), slow-release quantification is achieved and the condition that seedlings are burnt due to a sudden increase of the fertilizer in traditional single fertilization is avoided. In addition, loss of the fertilizer which is not absorbed is caused by single massive fertilization.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a slow-release and quantitative fertilization device, and also relates to a fertilization method of the slow-release and quantitative fertilization device. Background technique [0002] my country is a large agricultural country. With the improvement of agricultural technology, the output of various agricultural products has gradually increased. In agricultural technology, planting technology is also an important aspect to improve the quality and quality of agricultural products. In planting technology. [0003] In the traditional fertilization of crops, the method of base application and topdressing is generally used to ensure the fertilizer supply of crops at each stage. Although this method can solve the nutrient requirements of crops in different periods, in actual use, repeated topdressing leads to fertilizer The loss rate increases, the utilization rate decreases, and...
