Abstract
The invention discloses a preparation method of a foliar fertilizer promoting alfalfa seedling growth in acidic soil. The method comprises: first preparing a root growth solution, a mineral nutrient solution and an organic nutrient solution, then respectively taking 1-2ml of the root growth solution, 1-2ml of the mineral nutrient solution, and 3-5ml of the organic nutrient solution, mixing them and adding water to a constant volume to 1L, thus forming the foliar fertilizer. The foliar fertilizer prepared by the invention can effectively promote the growth of alfalfa seedling roots in strongly acidic soil, protect root activity and cell structures, relieve alfalfa seedling poisoning, and promote alfalfa growth. In a soil environment with pH of 4.5, the foliar fertilizer of the invention is utilized to treat alfalfa having an average plant height of 5cm. The foliar fertilizer is sprayed once every 10 days and 2 times in total. 1-2L/m<2> of the fertilizer is sprayed every time. After 30 days of treatment, the alfalfa root biomass is increased by 1.5-1.8 times compared with a control one, and the aboveground biomass is increased by 1.0-1.4 times compared with the control one.
Description
Technical field
What the present invention relates to is a kind of leaf leaven of agricultural technology field, specifically is a kind of foliage fertilizer preparation method who improves acid soil alfalfa growth of seedling.
Background technology
Red Soils in Southern China district soil generally presents strongly-acid (pH < 5.0); The g and D that suppresses the alfalfa root system, tip of a root passivation, the root hair is short and thick; The dietetic alimentation function reduces; And then suppress the alfalfa growth, cause that alfalfa plants is short, poor growth, output be very low, seriously restricted the geographic alfalfa plantation of Southern Red Soil soil.
At present, the relevant alfalfa that promotes is fewer at acid soil Study on Growth report, does not still have the otherwise effective technique measure.Literature search through to prior art finds that Guo Yanjun has reported that at " grass cultivation journal " the 15th volume 1 phase (84-89 page or leaf) in acid soil, adding lime regulates soil pH value, has obviously promoted the growth of alfalfa with yellow found the state (2006); Wang Xinhai etc. (2005) have reported to mend in the survey article of " Yunnan Prov Agriculture University's journal " the 20th volume 5 phases (705-709 page or leaf) and have executed the growth that boron fertilizer can improve roots of alfalfa in the acid soil.But be to use the lime cost of improving the soil very high, the feasibility that big area is used is low; And it is very limited to the amount of increase in production that promotes the acid soil clover to use boron fertilizer separately, and therefore, these two kinds of methods all are not widely used in actual production, does not find a kind of technical measures that can effectively promote the growth of acid soil alfalfa at present as yet.
Also find in the retrieval; One Chinese patent application number is: 200910135796.0; Denomination of invention is: a kind of efficient green foliage fertilizer and method for making thereof, this invention are a kind of efficient green foliage fertilizers: " it forms (in ton) by following proportioning: sodium nitrophenolate 8-10kg, α-Nai Yisuanna 2-4kg, an ammonium nitrate 70-90kg, Tripotassium Citrate 70-90kg, trace element (in metal) 9-12kg, choline dichloride 40-60kg, kaolin surplus.At first that sodium nitrophenolate, α-Nai Yisuanna and Tripotassium Citrate is even in stirrer for mixing, add other raw material then and evenly promptly get product of the present invention in stirrer for mixing.It has onset rapidly, the distinguishing feature of increase yield significantly, safety nuisance free." but this invention can't be used to promote acid soil alfalfa growth of seedlings.
Summary of the invention
The present invention is directed to the deficiency and the problem that exist in the background technology, a kind of preparation method who improves the foliage fertilizer of acid soil alfalfa growth of seedling is provided.The foliage fertilizer of the inventive method preparation is at China's soils in south china severe acidification (pH < 5.0); The khoai that alfalfa growing receives obvious inhibition uses; Can effectively promote the g and D of alfalfa seedlings root; Improve the absorptive function of root system, promote the growth of acid soil alfalfa nutrition.
