The invention discloses an astragalus smicus / straw organic fertilizer and a preparation method thereof. The preparation method includes the steps of taking astragalus smicus at the full-blooming stage and crop straw (preferably rice straw) as raw materials, properly dewatering the astragalus smicus and then grinding the same into pieces with length ranging from 1cm to 5cm, uniformly mixing the ground pieces with chopped crop straw according to the proportion (2.0-4.5) : 1 by fresh weight, inoculating 0-4.0% of organic material decomposing agent by dry weight of mixture, and then carrying out aerobic composting and fermenting by conventional methods. The aerobic composting and fermenting process can be controlled within 25 days, the organic matter content of the fertilizer is equal to or higher than 70%, the NPK total nutrient content is equal to or higher than 5.5%, and the germination index is equal to or higher than 105.0%. Therefore, the organic fertilizer not only has functions as conventional organic fertilizers and but also can be used as a seedling substrate substituting for the 40% turf.

The invention discloses a kiwi fruit low-yield orchard soil improvement method. The kiwi fruit low-yield orchard soil improvement method comprises the following steps of digging a circle of annular fertilization ditch at the position 0.8-1.0 m away from a kiwi fruit trunk, obliquely arranging the bottom surface of the fertilization ditch, enabling the depth of an inner side ditch to be slightly higher than a breathing root of a fruit tree, enabling the depth of an outer side ditch to be 5 cm higher than the depth of the inner side ditch, and enabling the width of the ditch to be 30-40 cm; applying a layer of astragalus sinicus powder with the thickness of 2 cm into the fertilization ditch, and backfilling planting soil with the thickness of 2 cm; inserting a plurality of chicken manure rods into the backfilled planting soil and the inner side surface of the fertilization ditch; laying a layer of L-shaped degradable water-absorbing fiber woven mesh, wherein the degradable water-absorbing fiber woven mesh is arranged on the chicken manure rods in a sleeving manner; and applying a layer of orchard waste powder with the thickness of 2 cm, conducting filling and leveling up with planting soil, and applying glycan polypeptide biological potassium. According to the kiwi fruit low-yield orchard soil improvement method, the granular structure of soil can be improved, nutrient elements are activated, the utilization rate of soil nutrients and fertilizers is improved, the nutrient absorption of the fruit tree roots is effectively promoted, and the growth of the fruit trees is promoted, so that the fruit yield and quality of a kiwi fruit low-yield orchard can be remarkably improved.

The invention discloses a method for inducing an astragalus sinicus tetraploid. The method comprises the following step: by using a combined mutagenic agent, performing dropping treatment on a growingpoint when a cotyledon-petiole included angle of a diploid astragalus sinicus ranges from 30 degrees to 50 degrees and a first true leaf is not released, wherein after the treatment, the optical density is reduced to 180 [mu]mol.m<-2>.s<-1>, the illumination time is controlled to be 10 h.d<-1>, the day temperature is 18 DEG C, the night temperature is 15 DEG C, and the relative humidity is 75% to90%; the combined mutagenic agent comprises 0.1 to 0.2% of colchicine, 50 to 100 mg.L<-1> of trifluralin, and 20 [mu]l.L<-1> Tween T-20; the treatment using the combined mutagenic agent is performedfor 2 to 4 times. According to the method, colchicine and trifluralin at specific concentrations are used in a mixed manner, so that the tetraploid induction rate reaches 13.7% and is improved; in addition, the concentration of colchicine is reduced, so that environmental pollution is reduced.

The invention discloses a method for regulating and controlling intercropping of sedum plumbizincicola and astragalus sinicus to restore farmland soil compositely polluted by heavy metal and organic pollutants. The method comprises the following steps: firstly, grinding sedum plumbizincicola with a hyperaccumulation effect on Cd, astragalus sinicus with an efficient rhizosphere degradation effect on organic pollutant PCBs, a leaf surface regulating agent abscisic acid with a growth stimulation effect on plants and a rhizobium inoculant with a promotion effect on degradation of PCBs on rhizosphere of astragalus sinicus; sedum plumbizincicola and astragalus sinicus are planted in the soil subjected to combined pollution in a greenhouse, and a pot experiment based on overground leaf surface regulation and underground rhizosphere strengthening remediation plant intercropping is carried out. The method is reasonable in design, simple to operate, economical and feasible, a bioremediation technology capable of improving the phytoremediation efficiency is ground out, and the method has the characteristics of no damage to the physical and chemical properties of the soil and no secondary pollution, can be applied to remediation of the heavy metal-organic pollutant combined contaminated soil, and has good environmental, economic and social benefits.

The invention discloses a method for repairing Cd contaminated soil by intercropping herbs and swamp cabbage. The method can repair Cd contaminated soil through intercropping agronomic measures. The method comprises: intercropping herbs and vegetables in Cd contaminated soil to be repaired, and carrying out normal cultivation management so that the Cd content in harvested vegetables and soil is reduced. The vegetables are swamp cabbages. The herbs are sorghum hybrid sudangrass, sudangrass, pennisetum, ryegrass, indian lettuce, chicory, amaranth, clover, alfalfa or astragalus sinicus. The invention provides the technical scheme for repairing Cd contaminated soil by agronomic measures of intercropping herbs in a swamp cabbage field. The intercropped herb has high biomass and a rapid growth rate, can enrich heavy metals such as Cd and can effectively reduce Cd content of the contaminated soil. The method can provide a basis for synchronous safe production and restoration in the Cd contaminated farmland. The method is environment-friendly and has obvious ecological, economic and social benefits.

The invention relates to a compound nutrition preparation for Astragalus sinicus as well as preparation and application thereof, and aims to solve the technical problem that high yield and stable yield are difficult to obtain due to the lack of targeted growth regulation and control means of Astragalus sinicus at present. The compound nutrition preparation contains effective components such as sodium borate, ammonium molybdate, monopotassium phosphate, paclobutrazol, 6-benzylamino adenine, brassinolide, sodium alginate oligosaccharide and the like. By spraying the compound nutrition preparation in the Astragalus sinicus cultivation process, and a high Astragalus sinicus seed yield and a high biological yield can be obtained. The compound nutrition preparation is low in preparation cost, simple and convenient to apply and stable in effect.
