Method of using vines to control invasion of exotic weeds
InactiveCN102428819AHas economic valueStrong stress resistanceHorticultureAgricultural engineeringEngineering
A method of using vines to control invasion of exotic weeds includes firstly, setting up sample plots in an exotic weed growing land, secondly, setting up a support, thirdly, making a bamboo basket, fourthly, preparing burnt soil, fifthly, preparing matrix mixture, sixthly, filling the bamboo basket, seventhly, growing plants, and eighthly, applying fertilizer. Allelopathy of exotic weeds can be prevented by using the bamboo basket to grow honeysuckle, kudzu and pumpkin, and the roots of the honeysuckle, the kudzu and the pumpkin can be protected from competitive inhibition of the exotic weeds. Raw materials are easy to obtain, the technique is simple and feasible, the exotic weeds are effective in control, and both ecological benefit and economic benefit are considered.

The invention relates to a special strawberry composite biological fertilizer as well as a preparation method and application thereof. The special strawberry composite biological fertilizer comprisesthe following components: EDTA-Ca (Ethylene Diamine Tetraacetic Acid), magnesium sulfate heptahydrate, EDTA-Mg, heptahydrate, EDTA-Zn, manganese sulfate monohydrate, EDTA-Mn, boric acid, EDTA-Fe, EDTA-Cu, soybean molasses, polyglutamic acid fermentation broth, chitosan oligosaccharide, algin, compound amino acid, humic acid, bacillus thuringiensis fermentation broth, bacillus megatherium fermentation broth, bacillus mucilaginosus fermentation broth and streptomyces jingyangensis fermentation broth. Through bacterium activation, seed liquid preparation, fermentation culture and compounding, thecomposite biological fertilizer is prepared, the composite biological fertilizer is applied to strawberry planting, and a diluted composite biological fertilizer liquid is sprayed at different growthstages of strawberry respectively. Due to synergetic effects of substances such as inorganic salts, organic matters and microorganisms, long lasting nutrient substances are provided to strawberry crops, absorption of nutrients in soil by plants is promoted, the fertilizer amount is reduced, and the chemical fertilizer cost is reduced.
