Description
Technical field
The present invention relates to fruit tree planting technique field, relate in particular to the growth regulator and the control method that improve peach fruit-setting rate.
Background technology
In recent years, for increasing economic efficiency, area and the output of the facility peaches such as greenhouse by solar heat, booth have a great development, and have promoted to a certain extent the progress of production model and technology.And in the process that technology is implemented, because peasant is eager to catch up with market and is impelled fruit early-maturing, and make that dormancy is not enough, the problem such as too fast that heats up is of common occurrence.For this reason, a lot of local with the control tree crown of deepling prune of the utmost point after gathering, if but prune not in time, flower bud differentiation is just incomplete.The bud of peach is autumn in summer differentiated, the summer of upper 1 year, start differentiation, until before Second Year blooms, through comprising the formation of ovary, the formation of the differentiation of pollen mother cell, ovule, the processes such as differentiation of the formation of pollen grain, filigree and pollen wall, a perfect flower with fecundity just really forms.Because the lasting time is long, the factor of influence being subject to is also many, especially the impact that is subject to plant nutrient status is larger, so, the output load of upper one year, rich water quality management, weather conditions etc., especially the height of stored nutrient level, directly affects quality that bud forms, blastular life-span and the effective length of pollination period.
Take nectarine as example, and existing Cultivation in Greenhouse nectarine ubiquity fruit fruit-setting rate is low, fruit is little, the problems such as aberration.In booth, cultivate nectarine, flowering stage and fruit development period are easy to occur serious fruit drop phenomenon.The reasons for the above problems be mainly that illumination condition is poor, pollination fertilization is bad, water and fertilizer management is improper and carbonic acid gas not enough etc.Green house applied nitrogen is too much, and young sprout pinching is in time added in branch excessive growth, has formed the nutrient competition between branch and young fruit, occurs the nutritional deficiency in the short time, causes physiological fruit drop.In order to prevent the excessive growth of branch, after spending, to young fruit expanding stage, set body and spray 200～400 times of liquid of 15% paclobutrazol wetting powder, can be compared with the physiological fallen fruit that effectively prevents from causing a large amount of nutrient losses to cause because of branch excessive growth.At young fruit period, to stone early stage, when young sprout grows to 5～10cm, stay 5 leaf pinching, when the secondary tip grows to 5～6 leaves, carry out again pinching.By in good time pinching, can more effectively weaken apical dominance, prevent that young fruit from coming off.1999, the research plant growth regulator such as the northwest Wang Fei of department of horticulture of agricultural university and trace element are beared fruit and the effect of fruit quality to precocious peach, result of study shows, 1000 times of liquid of 0.1% Brassinolide (BRS) soluble powder, can improve the fruit-setting rate of peach significantly.Now the physiological function of BRS is different from five large class plant hormones certainly, and it is prevalent in vegetative kingdom, is the active high novel plant endogenous hormones of a class, has confirmed that BRS mainly promotes elongation and the division of cell.BRS and other plant hormone are in close relations, have with growth hormone and act synergistically consumingly; BRS and gibberellin are independent and simple additions, and between abscisic acid, have anti-effect short of money consumingly.BRS can promote the raising of fruit-setting rate significantly, promotes the g and D of fruit.
And sprout to the florescence at bud, continuous high temperature is the main cause that causes fruit-setting rate to decline.Excess Temperature can cause bud rudiment too early, shortens Ovule Development, accelerates blastular abortion, and causing blooming, it is bad to bear fruit.The Differentiation and development of peach sexual cell is to complete the early spring before blooming, and the formation of sexual cell phase is very responsive to temperature, is prone to sexual organ degradation phenomena.After peach is removed natural dormancy, heat up and too fastly too highly easily cause that development of floral organs is too fast and that deformity occurs is abnormal.So, at facility, facilitate in ealy maturing culture, after finishing, dormancy should take the mode that heats up gradually, avoid heating up too fast, too high; At facility, delay in cultivation, should in bud, sprout to the florescence processing of lowering the temperature according to temperature condition, as shade and noon water spray, to avoid high temperature injury.
During blooming and bearing fruit, temperature of shed often can exceed normal range (NR), easily occurs flower phenomenon after first leaf, and peach fruit-setting rate is reduced greatly, even occurs the phenomenon of only blooming and not bearing fruit, and this is also the key point of greenhouse by solar heat facility peach production success or failure.For guaranteeing that facility peach normally bears fruit, before spending, after spending, respectively spray 100 times of liquid of 1 paclobutrazol, control is nourished and grown, and promotes reproductive growth.At young fruit " de-trousers " (while referring to that the grown peach young fruit of withered petal struts slightly), spray before efficiently to bear fruit for 1 time and expand spirit, promote reproductive growth, every 15-20 days, spray again 1 time, improve facility peach fruit-setting rate.
The open country peach garden fruit-setting rate of blooming in home is higher, does not generally have the not enough problem of fruit-setting rate.But in recent years, most areas spring temperature is fluctuated, particularly the peach blossom phase occurs surpassing continuously 25 ℃ and even surpasses 30 ℃ of temperature, then has again Snowfall, and temperature is straight up and down repeated multiple times, high temperature easily reduces pollen germination rate, easily promote the elongation of pollen tube, thereby disturb the growth of the normal development, particularly blastular of floral organ, and then cause fruit-setting rate low, especially 25 ℃ of above florescence high temperature are obvious especially; Yet low temperature suppresses again pollen tube growth impact fertilization, continuous many days high temperature of peach garden full-bloom stage or low temperature overcast and rainy day weather, will affect the solid process of Pollination Fertilization, and large-area temperature Change affect fruit-setting rate, the impact production of peach.
Therefore, solving the low problem of fruit-setting rate that the reasons such as peach garden and greenhouse florescence thermic anomaly cause, ensure high and stable yields, prevent and reduce natural disasters, is the production problem that should solve at present.
Summary of the invention
The object of the invention is, the defect existing for prior art, the growth regulator and the control method that improve peach fruit-setting rate are provided, solve the low problem of peach fruit-setting rate that the influence factors such as the florescence climatic anomaly, the flower bud development that exist in peach growth be not full cause, peach fruit-setting rate is improved.
