Description
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to a plant steady-state nutrition fertilizer.
Background
Agriculture is a human production activity that relies on land productivity to provide rich crops. However, land productivity is not endless and needs to be maintained and improved by proper management and maintenance. Among these, fertilizers play a critical role. Fertilizers are "nourishments" of crops, providing various nutrient elements necessary for plant growth. Through fertilization, farmers can compensate the consumption of nutrients in soil, and ensure healthy growth of crops, so that the yield and quality of agricultural products are improved. At the same time, agricultural practices also adversely affect the selection and use of fertilizers. Deep knowledge of the land and crops helps farmers select more suitable fertilizers, fertilizer is applied more reasonably, and larger agricultural benefits are obtained at lower environmental cost. Therefore, the relationship between agriculture and fertilizer is not just a simple supply and demand relationship, but a deep interaction and influence, and is a typical embodiment of harmony between human beings and nature. The steady-state plant nutrition fertilizer is a fertilizer technology, and provides comprehensive and balanced nutrition elements for plants based on steady-state growth theory of plants, so that the plants are promoted to realize steady and high-quality growth.
In the prior art, the fertilizer efficiency of the plant steady-state nutrition fertilizer can be influenced by environmental factors such as soil pH value, soil type, climate and the like, so that the solubility and effectiveness of nutrient elements in the fertilizer are reduced, and the absorption and utilization of nutrients by plants are influenced. In addition, since the nutrient elements in the plant steady state nutrient fertilizer are pre-mixed, if a certain element is excessive, the plant can not absorb other elements enough, thereby affecting the growth and development of the plant.
Disclosure of Invention
The invention aims to provide a plant steady-state nutrition fertilizer. The plant steady-state nutrition fertilizer is obtained by weighing humus, modified resin, potassium nitrate, potassium dihydrogen phosphate, active carbon, plant growth regulator and microbial agent according to parts by weight, adding the materials, mixing uniformly, and granulating.
The invention aims to solve the technical problems: the traditional plant stable state nutrition fertilizer has lower stability, and the nutrition elements in the plant stable state nutrition fertilizer are only applicable to specific plants.
The aim of the invention can be achieved by the following technical scheme:
The plant steady-state nutrition fertilizer comprises the following raw materials in parts by weight: 50-80 parts of humus, 60-80 parts of modified resin, 10-15 parts of potassium nitrate, 10-15 parts of monopotassium phosphate, 5-10 parts of activated carbon, 1-3 parts of plant growth regulator and 1-3 parts of microbial agent.
Further, the humus is prepared by the following steps:
crushing peel, vegetable residues and biomass waste, uniformly mixing with garden soil, composting for 10-30d, controlling the humidity to be 50-60% to obtain pretreated biomass, placing the pretreated biomass into a composting tank for layering and stacking, adding orange peel between each layer, absorbing generated peculiar smell, turning over every 7d, controlling the humidity to be 40-60%, controlling the central temperature of the composting tank to be 60-70 ℃, performing after-ripening treatment when the central temperature of the composting tank is reduced, turning over every 24h, and sieving by a 200-mesh sieve after composting for 7-10d to obtain humus.
Further, the modified resin comprises the following steps:
dispersing polyvinyl alcohol in distilled water by ultrasonic, placing into a stainless steel polytetrafluoroethylene lining reaction kettle, adding sodium alginate while stirring under the protection of nitrogen, dropwise adding N-methyl-2-pyrrolidone, adding boric acid, controlling the temperature at 90-100 ℃, adjusting the pH value to 3-4, reacting for 3-5h, adding bentonite, stirring for 1-3h, cooling to room temperature, standing for 15-30 min, filtering, washing, and drying to obtain sodium alginate modified polyvinyl alcohol-loaded bentonite, namely the modified resin.
The microbial agents comprise one or more of rhizobium inoculant, azotobacter inoculant, phosphate-dissolving microbial inoculant, silicate microbial inoculant, photosynthetic bacteria inoculant, growth promoting inoculant and bioremediation inoculant.
The plant growth regulator comprises one or more of auxin, gibberellin, cytokinin, ethylene generator, abscisic acid and brassinolide.
The biomass waste comprises one or more of kitchen waste, straw, rice bran, sawdust and grass meal.
The mass ratio of the pericarp, vegetable residue and biomass waste is (1-1.5): (2-3): (3-6).
The mass ratio of the polyvinyl alcohol to the sodium alginate to the N-methyl-2-pyrrolidone to the boric acid to the bentonite is (20-30): (10-15): (3-5): (4-6): (15-17).
The invention has the beneficial effects that:
1. In the technical scheme of the invention, sodium alginate has negative charges and partially protonated polyvinyl alcohol with positive charges interact to drive the sodium alginate and the partially protonated polyvinyl alcohol to be tightly combined, a stable network structure is further formed through hydrogen bonds, silicate layers of bentonite are combined through weak interaction force, and a sodium alginate-polyvinyl alcohol compound can be inserted between the silicate layers to form an intercalation structure, so that the overall stability and adsorption capacity are further enhanced. The characteristic of the composite structure endows the fertilizer with slow release performance, so that nutrient substances are slowly and continuously released into soil, durable nutrient supply is provided for plants, nutrient loss is reduced, and the stability of the fertilizer is enhanced.
2. According to the technical scheme, the modified resin can preserve nutrient elements provided by humus and nitrogen, phosphorus and potassium in the fertilizer, and reduce fixation and loss in soil, so that the fertilizer utilization efficiency is improved. In addition, the plant steady-state nutrition fertilizer can improve the soil structure through the modified resin, increase the water retention and the air permeability and create a more superior growth environment for plant roots. The fertilizer can reduce nutrient leaching loss and runoff, reduce adverse effects on the environment, and enhance stress resistance of plants, so that the fertilizer can better cope with various environmental pressures.
3. According to the technical scheme, the modified resin, the nitrogen-phosphorus-potassium salt, the active carbon and the humus are compounded, so that universal nutrient elements can be provided for plants, the activities of soil microorganisms are promoted, and the growth and development of plant root systems are facilitated. The plant growth regulator and the microbial agent are used for regulating the growth and development process of plants for plant growth, improving the microbial environment of soil and promoting the decomposition of soil organic matters and the transformation of nutrients.

Three plants of corn, rose and spinach were planted in soil under the same conditions, respectively, and for each plant, examples 5-7 and comparative example 1 were each separately provided, and a blank set of comparative examples was additionally provided. The same amount and frequency of fertilization were set, and plant growth parameters (plant height, leaf area and yield) were measured weekly, examples 5 to 7 were recorded as an implementation group (implementation group takes the average value of examples 5 to 7), comparative example 1 was recorded as a control group, and blank control was recorded as a blank group. The growth of the plants was recorded and compared and the results are shown in table 1:
TABLE 1 growth of plants of each group
Fertilizer contribution = (fertilized crop yield-no fertilized crop yield)/fertilized crop yield x 100% in table 1. Based on the plant growth parameters of table 1, fertilizer applicability evaluation criteria were set as shown in table 2:
table 2. Suitability evaluation criteria (after fertilization)
Comprehensive evaluation was performed according to table 2, and if at least two parameters of plant were "excellent" in three parameters of plant height, leaf area and yield, and the remaining parameters were not lower than "good", the fertilizer was considered to have "high applicability" to the plant; if the plant is "good" or above in most of the three parameters, the fertilizer is considered "moderately applicable" to the plant; fertilizer is considered "less applicable" to a plant if the plant is mostly "normal" or below in three parameters.
The suitability evaluation of the implementation group and the comparison group is shown in table 3:
TABLE 3 evaluation of applicability of the control and the control groups
As can be seen from tables 1 and 2, the fertilizer contribution rate of the embodiment in three plants of corn, rose and spinach is greater than that of the comparative group, and the applicability evaluation is superior to that of the comparative group as a whole, which means that humus, modified resin, potassium nitrate, monopotassium phosphate, active carbon, plant growth regulator and microbial agent are weighed according to parts by weight, added into a mixture, uniformly mixed and granulated to obtain the plant steady-state nutritional fertilizer, which has good applicability and is beneficial to improving the growth and development of plants.
