Abstract
The invention discloses a method for promoting fruit setting of jujube trees in arid regions and a special preparation of the method. According to the method for promoting the fruit setting of the jujube trees in the arid regions and the special preparation of the method, 5-aminolevulinic acid, bromine, thidiazuron, boric acid, FeSO4CuSO4, zinc sulfate, manganese sulfate and sodium sulfate are prepared to form a solution with the concentration of 0.2% to 0.4%; and the solution is sprayed on the jujube trees in 15 to 25 days after the jujube trees start to blossom. Compared with a traditional method, the method for promoting the fruit setting of the jujube trees in the arid regions and the special preparation of the method have an obvious promoting effect on the fruit setting, the fruit setting rate is generally improved by 35%, the fruit protection rate is particularly and remarkably improved, and the commodity rate of jujube fruits can be improved remarkably; and meanwhile, the mixed preparation is composed of biological agents and inorganic substances, is harmless to human body and high in safety, has the advantages of being convenient to use and stable in effect, and has quite broad application prospects.
Description
Technical field
The present invention relates to jujube high-yield culturing field, more particularly, relate to for the arid area and promote method and the special-purpose plant growth regulator of the method that jujube tree bears fruit.
Background technology
Jujube tree is the peculiar economic tree of China, and area has reached 1,500,000 hectares at present, is the first dry fruit tree variety of China.In recent years Xinjiang becomes emerging jujube tree artificial planting district because of its natural environment regional superiority, the red date quality of producing high.Though but the jujube flower amount is large, natural fruit-setting rate is 2% left and right only, and especially florescence humidity too low (lower than 50%) can suppress the Chinese date pollen germination, and the hot weather of arid biogeographic zone is beared fruit totally unfavorable to jujube tree, cause output too low, has restricted the jujube industry and has developed in a healthy way.
In existing known technology, most widely used is Spraying in the flowering stage GA
3, this class medicament originates in the discovery of the growth hormone thirties in 20th century, and growth hormone ubiquity, content in plant corpus is atomic, is the necessary material of plant growth.GA
3Be that broad spectrum type promotes growth substance, jujube tree is promoted to bear fruit successful, hang tachyauxesis and form nutrition and unexpectedly strive but easily cause jujube, cause the young fruit of sitting easily to come off, especially to be subjected to air humidity to affect application effect unstable for arid biogeographic zone.Excessive or repeatedly use the jujube fruit disease evil that causes and can increase the weight of, cause jujube fruit matter to descend, therefore part jujube district begins to forbid GA at present
3
In promoting the conditioning agent that jujube tree bears fruit, 6-BA, B9,2,4-D, IAA etc. also has certain effect, also as seen uses GA
3Share a kind of with it, but all exist more or less young fruit to come off and problem that quality descends.
Summary of the invention
The objective of the invention is to provide a kind of method and special-purpose plant growth regulator of the method that arid area jujube tree promotion is beared fruit that be applicable to.
The objective of the invention is by following process implementation: get the 5-ALA(5-amino-laevulic acid) 5～50 weight portions, Br (brassin lactones) 1～30 weight portion, TDZ(Thidiazuron) 0～1 weight portion, H

420～50 weight portions, Na
2SO
45～10 weight portions are as compound formulation, and the used time adds water with described compound formulation, and to be mixed with concentration be that 2～4 ‰ solution sprays jujube tree.
The above-mentioned time that sprays is 15～25 days after jujube tree begins to spend, and crosses prosperous the impact and bears fruit for preventing tree vigo(u)r, forbids within 10 days before spraying that the jujube garden pours water, and specifically sprays the morning or that are arranged in fine day the dusk time-division.
Above-mentioned and spray front 3～5 days and preferably carry out girdling, namely with cutter or specific purpose tool, the trunk phloem being made 1～3 annular cuts off: at 15～20cm place, distance ground, carry out girdling one circle with cutter or specific purpose tool, annular is cut off wide 0.2～0.5cm, 4～the 6cm of being separated by between each annular is cut off, the up and down edge of a knife preferably is low inside and high outside slope shape, in case ponding is easy to again healing.
After above-mentioned spraying, repeat spraying was once again in 5～8 days.
Above-mentioned spraying as meeting rain in spray in rear 24 hours, should repeat spraying once.
If jujube tree early stage, growing way was excessively prosperous, can be again adding water with 5-ALA, to be mixed with concentration be that 2～4 ‰ solution sprays separately 1～2 time jujube tree, and in order to suppressing growing way, the time that sprays is after above-mentioned compound formulation sprays 1～5 day.
Above-mentioned morning or be divided into 7 of local time at dusk the time before or 20 laggard behaviors best.
The special preparation that method of the present invention is used, formulated by the material of following components by weight percent: 5-ALA:5～50 weight portions, Br:1～30 weight portions, H

4Be dissolved in suitable quantity of water as preparation 2, again preparation 1 and preparation 2 mixing and water addings be mixed with concentration during use and be 2～4 ‰ solution and spray.
TDZ in above-mentioned preparation preferably packs separately, according to circumstances adds in use use.
Above-mentioned special preparation is preferably made separately 1～2 packing as standby again with described 5-ALA, and each is packaged as 5～100 weight portions.
Use GA 3 preparation 20ppm solution: growth of young is more than 12 days to the required number of days of 5mm, and fresh pod yield is 576.35 kg/ mus, commodity fruit rate 83.12%.
Use preparation of the present invention: growth of young is about 7 days to the required number of days of 5mm, and fresh pod yield can reach 827.13kg/ mu, commodity fruit rate 95.98%.
Table 1 is contrast experiment's situation of using method of the present invention and special preparation and use GA3 preparation to carry out.
Can find out from experiment, method and formulation of the present invention is compared with conventional method, and facilitation effect is clearly arranged bearing fruit, generally surpass 35%, particularly the raising of fruit retention rate is especially obvious, and low has also surpassed one times, and can significantly improve the commodity rate of jujube fruit.
compared with prior art, the present invention replaces GA3 with 5-ALA, pass through simultaneously 5-ALA, BR, the synergy of TDZ etc., having avoided the unitary class hormones such as alone GA3 to make the unbalanced and jujube of young fruit internal hormone hang growth causes the competitive scope of flowers and fruits nutrition and comes off in a large number, replenish simultaneously required B of florescence, Fe, Cu, Mn, Zn, the elements such as Na, make comparatively equalization stable of young fruit internal hormone level, effectively prevented coming off of young fruit, simultaneously can strengthen flowering fruit bearing stage jujube tree anti-adversity ability, alleviate the too low adverse effect to bearing fruit of arid area jujube tree florescence air humidity, improve the bear fruit nutritional condition of rear young fruit development of jujube tree, promote the jujube fruit to grow rapidly, make young fruit development speed fast, be difficult for shedding, not only can bear fruit the time in advance, realization is pressed tree with fruit, control growing way, and can improve increasing of single fruit weight and soluble solid, improve fruit quality, simultaneously, compound preparation of the present invention is comprised of biologic product and inorganic matter, harmless, safe, have easy to use, the advantage of effect stability, application prospect is very wide.
