The planting method is characterized in that base fertilizers applied when seeds are sown are compound biological bacterial fertilizers comprising inorganic compound fertilizers and organic biological bacterial fertilizers which are mixed with one another. The planting method has the advantages that the biological bacterial fertilizers in the applied base fertilizers can continuously release nutrients after being decomposed, so that the photosynthesis of crops can be promoted, a nutrient element utilization rate can be increased, a yield increasing effect is obvious, the planting method is wide in applicability and is non-toxic and harmless, the stress tolerance of the crops can be improved, and environmental pollution can be prevented; soil can be activated by the applied base fertilizers, the structure of the soil can be improved, the water storage and fertilizer conservation ability and the permeability of the soil can be enhanced, the soil fertility is developed and can be durable, and nutrients can be timely supplemented to the soil by the inorganic fertilizers in the base fertilizers.
Description
Technical field
The present invention relates to the cultivation method of a kind of crops, particularly relate to a kind of implantation methods that improves corn yield.
Background technology
Corn also claims maize, maize, maize, ear of maize, is the annual gramineae herbaceous plant, belongs to grass family maize family Zea maize seed, Chinese first cereal crops, and main producing region is positioned at large corn belt, third place in the world---corn belt, Chinese Pine the Liao Dynasty Plain.Approximately 1249.35 square kilometres of the total cultivated areas of corn, be important cereal crops and important feed resource, is also the highest cereal crops of whole world gross yield.Corn is a kind of staple food material, have the laudatory title of life prolonging food, the effects such as fat-reducing longevity are arranged, is the class that nutritive value is the highest, vitamin content is rice, wheat 5-10 times, also contain various trace elements, corn contains abundant cellulose, not only can stimulate enterocinesia, prevent constipation, can also promote the metabolism of cholesterol, accelerate the discharge of enterogenous endotoxin, there is the great potential of the high nutrition of exploitation, high biological function food.Be vegetative period and tasseling stage the period that the growth and development stage of corn needs most nutrient supply, generally being in great demand and the trace elements such as the calcium of some, magnesium, sulphur to nitrogen, phosphorus, potassium in these periods, but the mutual antagonism of the absorption of calcium and magnesium, potassium element, magnesium, potassium calcium at most are few.In addition, because the plantation distribution of corn is the widest, area is maximum, so the physicochemical property of soil is more various, plantation throughout the year in addition, the structure of soil is destroyed, and the fertility of depending merely on soil can't meet the demand of crop to nutrition, yet the existing chemical fertilizer of using is all single composite fertilizer.Inorganic composite fertilizer or organic biofertilizer, inorganic composite fertilizer refers in nitrogen, phosphorus, three kinds of nutrients of potassium, the inorganic fertilizer of only being made by chemical method that at least contains two kinds of nutrients, cause crop to obtain a kind of goods of specific fertilizer effect and organic biofertilizer is vital movement with microorganism; The long-term excessive chemical fertilizer of using single type can make soil compaction, makes the soil acid-base imbalance, crop failure, and Quality Down, and also infiltration rate is slow, is subject to the influence degree of the factors such as soil physico-chemical property and temperature high, and effect of increasing production is not remarkable.Therefore, providing a kind of implantation methods that improves corn yield, is the industry focus focused on and a difficult problem that is difficult to break through.

Comparative example 1
Commercially available nitrogen phosphorus potassium 15-15-15 inorganic composite fertilizer 50kg are administered to before corn seeding as base manure on one mu of soil, were then executing maize planting on the soil of this fertilizer.Growth and development stage is by the commercially available Lay shield of blade spraying pancebrin fertilizer.
Comparative example 2
Corn seed 4kg adds water 100g with the fertile 20g of commercially available Lay shield pancebrin prior to seeding and is dressed seed, commercially available nitrogen phosphorus potassium 15-15-15 inorganic composite fertilizer 50kg are administered to before corn seeding as base manure on one mu of soil, were then executing maize planting on the soil of this fertilizer.Growth and development stage is by the commercially available Lay shield of blade spraying pancebrin fertilizer.
Described each component of one of embodiment 1-6 is commercially available prod, and each amounts of components is increased or reduces according to same ratio, and the parts by weight relation of each component of gained all belongs to protection scope of the present invention; The collocation method of the described solution A of one of embodiment 1-6, solution B and solution C all refers to the simple mixing of each component.
The implantation methods of embodiment 1-6 and comparative example 1-2 is respectively used to varieties of plant for first beautiful 335 corn, and two stages of time-division of topdressing carry out: 1. vegetative period: when corn grows to the 80cm left and right on Gansu Province, liquid fertilizer 150g is watered to the 30kg foliage-spray; 2. tasseling stage: liquid fertilizer 200g is watered to the 20kg foliage-spray.Fertilization effect sees the following form.
Upper table shows that to use composite biological fertilizer more taller than not only using common inorganic composite fertilizer but also using the crop yield of common liquid fertilizer as base manure, especially uses the fertilizer of embodiment 6 proportionings, and output is the highest.This be because the organic biofertilizer in composite biological fertilizer can activating soil, the improvement soil structure, cultivate soil fertility, and be rich in various trace elements, fertilizer efficiency is lasting, after being manured into soil, after decomposing, microorganism discharges endlessly various nutrients for the Maize Absorption utilization, can also constantly discharge carbonic acid gas, improve the photosynthesis of corn; The humus that fertilizer forms in soil has multiple buffer capacity and permeability, the various organic acids that produce after decomposing, the carbon source that inorganic acid is edaphon, impel its activity, then be combined with inorganic fertilizer to use and supplemented in time soil nutrient, because inorganic composite fertilizer mostly is alkalescence, and organic biofertilizer mostly is acid, the palpus matching while using, both are combined with, and learn from other's strong points to offset one's weaknesses, emergency is helped mutually, gives full play to the yield potential of fertilizer.
The crop that above-described embodiment obtains is the plump length of vegetative period well developed root system, blade, drought-resistant ability enhancing, utmost point Resistance To Helminthosporium Turcicum, not living aphid, the tasseling stage maturing stage in advance, full seed, completely filled fruit degree improve, thousand corn weight increases, output improves, and the resistance against diseases of corn obviously strengthens; The usage amount of this fertilizer is very little, and because of its foliage-spray, infiltration rate is fast, utilization rate of fertilizer is high, saves production cost.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
