Abstract
The invention relates to a liquid fertilizer which is urea aqueous solution added with chitosan, wherein the concentration of chitosan is 2-4% by massic volume. The chitosan is water-soluble chitosan such as carboxymethyl chitosan. Bacillus subtilis or Chinese herbal medicine extract liquid prepared from tripterygium wilfordii, calamus and lemongrass is selectively added into the liquid fertilizer provided by the invention. The fertilizer provided by the invention can effectively promote the growth rate of crop and keep the nutrient balance of the crop. The component with an insecticidal effect is added into the fertilizer, thereby effectively reducing the pest and disease damage of the leaf surface when being applied to the leaf surface.
Description
Technical field
The invention belongs to Yu Haiyang material applied technical field, be specifically related to a kind of liquid fertilizer that contains chitosan and urea.
Background technology
China is a large agricultural country, and the volume increase of agricultural, increases income the application that be unable to do without chemical fertilizer.But the use of chemical fertilizer is when improving crop yield, also brought soil compaction, the disadvantage such as residual in agricultural-food.The soil application situation of present China biases toward chemical fertilizer and drops into, but the utilization ratio of chemical fertilizer does not but improve, because the excessive usage quantity that blindly adds large chemical fertilizer makes chemical fertilizer utilization ratio have a declining tendency on the contrary.Although use farm manure can overcome the problems such as soil compaction, chemical residual.But farm manure quantity does not satisfy the requirement of extensive use, and traditional farm manure can cause the propagation of pathogenic micro-organism and parasite (ovum) because heap fermentation is incomplete, and the problem such as nitrogen loss.
Chitosan (chitosan) is to be obtained through deacetylation by the chitin (chitin) that nature extensively exists, and chemical name is Chitosan (1-4)-2-amino-B-D glucose, also is referred to as chitin.Can from the shell of ocean shrimp crab class, prepare by chemistry or biological method, therefore, have inexhaustible resource.But at present the application in the organic fertilizer field is not also effectively carried out for chitosan, and therefore, searching can partly or entirely replace chemical fertilizer, and the novel chitosan fertilizer with farm manure Effect of improving soil just seems extremely important.
Summary of the invention
The purpose of this invention is to provide a kind of liquid fertilizer that contains chitosan and urea, thereby remedy the deficiencies in the prior art.
Liquid fertilizer of the present invention, for being added with the aqueous solution of urea of chitosan, wherein the quality concentration of volume percent of chitosan is 2-4%.
Described chitosan is water-soluble chitosan, for example cm-chitosan.
The quality concentration of volume percent of used aqueous solution of urea is 4-6%.
Also be added with subtilis in the above-mentioned liquid fertilizer, the concentration of interpolation is 1 * 10
3-10
4Cfu/ml.
In addition, the anti-microbial effect that the subtilis of above-mentioned interpolation plays can also substitute with the aqueous extract of herbal medicine, and the mass fraction of its interpolation is 20～30.
The aqueous extract of described Chinese medicinal herbs is to obtain lapping powder after trypterygine, calamus and Herba Cymbopogonis Citrari are ground, and the rear filtration that is added to the water is again made; Lapping powder is that the 20-30% rear filtration that is added to the water is made by mass volume ratio g/ml.The mass fraction of trypterygine, calamus and Herba Cymbopogonis Citrari is respectively 10～30,20～50,30～50.
Fertilizer of the present invention can effectively promote the growth velocity of crop, keeps Crop nutrient balance.The composition with insecticidal effect that adds in fertilizer when carrying out foliage-spray, can effectively reduce the blade face disease and pest.
Embodiment
Liquid fertilizer of the present invention is the aqueous solution of urea that is added with chitosan, and the interpolation concentration of chitosan and the concentration of aqueous solution of urea have been carried out long-term optimization, thereby the viable bacteria that guarantees subtilis can survive in liquid fertilizer.Used subtilis is nontoxic to people and animals, free from environmental pollution, it can produce multiple antibiotic and enzyme, has broad spectrum antibiotic activity and extremely strong anti-adversity ability, to demonstrating good disease-controlling effect on the farm crop such as cotton, wheat, capsicum, tomato, corn, fruit tree.
The chitosan that fertilizer of the present invention is used can be selected commercially available water-soluble chitosan product, for example is the water-soluble chitosan of the method preparation in the patent of invention of CN 1283634A according to publication number.
Urea is arbitrary commercially available prod, and the complex role that focuses between component of the present invention is not done concrete restriction for the source of component.
Below in conjunction with specific embodiment fertilizer of the present invention is described in detail.
Embodiment 1:
Get 40g urea 1000ml water dissolution, after fully stirring, add again the cm-chitosan of 40g, stir and make water soluble fertilizer.
Embodiment 2:
Get 60g urea 1000ml water dissolution, after fully stirring, add again the cm-chitosan of 30g, stir and make water soluble fertilizer.
Embodiment 3:
Get 40g urea 1000ml water dissolution, after fully stirring, add the cm-chitosan of 40g again, stir and make water soluble fertilizer, then add the subtilis bacterium liquid of preparation, the concentration that makes subtilis in the liquid fertilizer of making is 1 * 10
3-10
4Cfu/ml.
Subtilis can be selected the bacterial strain of using in the agricultural, the viable bacteria bacterium powder of for example selling on the market.
Embodiment 4:
Get 40g urea 900ml water dissolution, after fully stirring, add again the cm-chitosan of 40g, stir and make water soluble fertilizer, add again the extracts of Chinese herbal medicine of 100ml.Wherein the preparation method of the aqueous extract of Chinese medicinal herbs is as follows: 100g trypterygine, 300g calamus and 300g Herba Cymbopogonis Citrari are cut into to grind behind the segment obtain lapping powder, is that extracts of Chinese herbal medicine is made in the 20-30% rear filtration that is added to the water with lapping powder by mass volume ratio g/ml.
Fertilizer of the present invention can apply fertilizer by the mode of foliage-spray or filling root, is applicable to the economic species such as flowers, fruit tree, vegetables.Result of use shows, sprays when seedling stage, flowering period, young fruit expanding stage and the plant strain growth of plant are bad.Fruit growth is accelerated, and the ripening stage shifts to an earlier date, and fruit colour is good, and has obvious effect of increasing production.
Use the fertilizer of embodiment 1 preparation to fill with root fertilizer in the seedling stage of tomato, fertilising twice in interval 15-20 days, can improve output and reach more than 10%.In florescence or young fruit period fertilising, can improve output 15-20%.
But owing to having added the aqueous extract of the Chinese medicinal materials of subtilis or insect protected in the fertilizer of the present invention, can be used for driveing the foliar pest of plant.After foliage-spray used, the insect number on the plant obviously reduced.Foliage-spray after being added with the fertilizer of aqueous extract of Chinese medicinal materials, the strain of detectable band worm obviously reduces, and has effectively suppressed the generation of disease and pest.Fertilizer with embodiment 3 or embodiment 4 preparations carries out leaf dressing to eggplant, except having improved production rate and output, has also effectively reduced the quantity of insect on the blade face, thereby the number of times of spraying insecticide is reduced greatly.
