Abstract

The utility model discloses a special-purposed controlled-release compound fertilizer for peanuts, which comprises a granular fertilizer (1), wherein the exterior of the granular fertilizer (1) is sequentially wrapped up by a controlled-release nitrogen layer (1) and an organic film layer (2). The special-purposed controlled-release compound fertilizer meets the fertilizer needing requirements of the peanuts at different stages and is in line with the soil characteristics and the fertilizer needing rule of the peanuts by sequentially wrapping up the controlled-release nitrogen layer and the organic film layer outside the granular fertilizer; and by adopting the reasonable formula and proportion of the special-purposed controlled-release compound fertilizer, the occurrence of phenomena such as single pip, blighted fruits, hollow fruits of the peanuts and the like are effectively avoided and the quality and yield of the peanuts are improved.

Description

Peanut special slow release composite fertilizer

Technical field

The utility model relates to a kind of compound manure, relates in particular to the special slow release composite fertilizer of cultivating peanut.

Background technology

In peanut high yield and high quality cultivation management, fertilising is one of the most resultful measure.Peanut is relevant with the growth period of peanut to the absorbed dose of nitrogen, phosphorus, potassium element, its micro-absorption principle is: nitrogen, phosphorus, the potassium absorbed dose in seedling phase, full fruit phase and ripening stage are few, and many in nitrogen, phosphorus, the potassium absorbed dose of bloom following pin phase and fruiting period.Therefore, in peanut fertilising process, meet the peanut different growing stage grow required trace element with and the fertilizer of rational proportion be the key that influences the quality and yield of peanut.

In the prior art, the fertilizer that generally adopts in the peanut fertilising is conventional fertilizer, and the difficult control of its micro-kind and corresponding mixture ratio is difficult to meet required trace element in the peanut different growing stage process of growth in the fertilising process.Thereby, in the peanut process of growth because of improper fertilization regular meeting phenomenons such as single fruit benevolence, not plump fruit, empty fruit take place, have a strong impact on peanut quality and output.

Therefore, the dedicated fertilizer that satisfies the required trace element of peanut different growing stage has become those skilled in the art assistant officer's technical problem to be solved to improve peanut quality and output.

The utility model content

The purpose of this utility model is to have proposed the special slow release composite fertilizer of cultivating peanut, and it has satisfied the required various trace elements of peanut different growing stage supplies with, and has improved the quality and yield of peanut.

In order to achieve the above object, the utility model proposes the special slow release composite fertilizer of cultivating peanut, comprise particle fertilizer, bundled slow-releasing nitrogen layer and organic film successively outside particle fertilizer.

Preferably, the weight percent of nitrogen, phosphorus, potassium is 11: 18: 9 in the particle fertilizer.

Preferably, be wrapped in the fertile outer field slowly-releasing nitrogen layer of particle and account for 5% of slow-release compound fertilizer gross weight.

Preferably, being wrapped in the outer field organic coated layer main component of slowly-releasing nitrogen layer is non-polar low molecular weight organism or non-polar polymer rete.

Compared with prior art, the utlity model has following beneficial effect:

1, by being wrapped with slowly-releasing nitrogen layer and organic film at particle fertilizer, the trace element of the fertile rational formula ratio of particle has satisfied the required trace element of peanut different growing stage and has supplied with, avoided in the conventional fertilizer operation of available technology adopting phenomenons such as single fruit benevolence, not plump fruit, empty fruit usually taking place, having improved influences peanut quality and output.

2, by thickness adjustment control nitrogen, phosphorus, the potassium release of organic coated layer,, meet the soil characteristic and the regulation of fertilizer requirement of peanut with multiple middle micro-slowly persistent discharging required in the peanut process of growth, improve the utilization ratio of nutrient.

3, three-layer composite structure of the present utility model, trace elements such as nitrogen, phosphorus, potassium can discharge slowly, thereby have reduced the number of times of fertilising, have a saving of labor, save time, efficiently, characteristics such as environmental protection.

Description of drawings

Fig. 1 is a structural representation of cultivating peanut special slow release composite fertilizer that the utility model proposes.

Embodiment

Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.

As shown in Figure 1, be a structural representation of cultivating peanut special slow release composite fertilizer that the utility model proposes, the soil characteristic and the regulation of fertilizer requirement of root a tree name peanut, each slow-release compound fertilizer particle are composited by grains dedicated fertile 1, slowly-releasing nitrogen layer 2 of peanut and organic coated layer 3 three-decker from inside to outside.

Wherein, particle fertile 1 is the grains dedicated fertilizer of peanut, and particle fertile 1 is for containing the fertilizer of nitrogen, phosphorus, potassium and middle trace element in the utility model embodiment, and wherein the weight percent of nitrogen, phosphorus, potassium is 11: 18: 9.Be wrapped with slowly-releasing nitrogen layer 2 at particle fertilizer 1, slowly-releasing nitrogen layer 2 is sprayed on the surface of particle fertilizer 1, can regulate the nutrients ratio of nitrogen, and nitrogen accounts for about 5% of slow-release compound fertilizer gross weight, can arrange in pairs or groups mutually with the nitrogen fixation of peanut rhizobium, for the growth of peanut provides competent nutrient.At the organic coating layer 3 of the top layer of slowly-releasing nitrogen layer 2 spraying parcel, its main component is non-polar low molecular weight organism or non-polar polymer rete.

The peanut special slow release composite fertilizer that in the utility model embodiment, provides, the trace element of the fertile rational formula ratio of particle satisfies trace element in the required nitrogen of peanut different growing stage, phosphorus, the potassium etc., effectively avoid the generation of phenomenons such as peanut single fruit benevolence, not plump fruit, empty fruit, improved the quality and yield of peanut.By can control the release of nitrogen, phosphorus, potassium nutrition to the adjustment of organic coated layer 3 thickness, with slow persistent the discharging of multiple middle trace element required in the peanut process of growth, improve the utilization ratio of nutrient, meet the soil characteristic and the regulation of fertilizer requirement of peanut.In addition, three-layer composite structure of the present utility model, trace elements such as nitrogen, phosphorus, potassium can discharge slowly, have satisfied the micro-demand of peanut different times, thereby have reduced the number of times of fertilising, have a saving of labor, save time, efficiently, characteristics such as environmental protection.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.

Claims

1. the special slow release composite fertilizer of cultivating peanut is characterized in that: comprise particle fertilizer (1), bundled slow-releasing nitrogen layer (2) and organic film (3) successively outside particle fertilizer (1).
