Description

Improve the method for peach fruit-setting rate under Protected Cultivation

Technical field

The present invention relates to fruit growing field, be specifically related to a kind of method that improves peach fruit-setting rate under Protected Cultivation.

Background technology

At present, fruit tree adopts the situation of greenhouse cultivation more and more, can conveniently control the growing environment of peach, improve its survival rate and fruit-setting rate, and can effectively control the sugariness of fruit, there is good practical value, if but the planting environment in booth is controlled bad, can play reaction, affect growth and the result of peach.

Summary of the invention

The object of the present invention is to provide a kind of method that improves peach fruit-setting rate under Protected Cultivation, for the growth of peach provides suitable growing environment, the generation of preventing disease and pest effectively in advance, improves survival rate, fruit-setting rate and the fruit quality of peach, has good promotional value.

The present invention is achieved by the following technical solutions, a kind of method that improves peach fruit-setting rate under Protected Cultivation, and its concrete steps are:

1. temperature is controlled, and from button canopy is warming up to and blooms, in canopy, maximum temperature is forbidden to surpass 25 ⁰c, minimum temperature can not be lower than 4 ⁰c, guarantees that the vernalization phase is more than 40 days, to guarantee Pistil And Stamen normal development; Florescence, temperature of shed was forbidden to surpass 20 to spending latter 7～10 days ⁰c～22 ⁰c, minimum temperature can not be lower than 5 ⁰c;

2. create suitable pollination condition, to guarantee pollination, fertilization; The measure of supplementary pollination has artificial pollination, or places the special-purpose honeybee of pollination or common honeybee, and every mu of canopy ground can discharge wall honeybee or one case common honeybee of 500 left and right, meanwhile, strictly air humidity is controlled to 50% left and right;

3. comprehensive regulation tree vigo(u)r, prevents or alleviates physiological fallen fruit, 1) bud stage, according to tree vigo(u)r, is used 100～200 times of paclobutrazol integrated control aphids, sticky leaf worm; 2), after bearing fruit, higher due to temperature of shed, humidity, a little less than illumination, Chang Yi causes empty prosperous excessive growth, causes serious physiological fallen fruit, for after preventing from that this phenomenon from occurring, can take following measures: a. to thank spending to stone before the phase, Controlled irrigation amount, not nitrogen fertilizer application; B. carry out in time sublateral shoot pinching; C. thank and spend latter 3～5 days, 300～400 times of 15% paclobutrazol of foliage-spray, fruit-setting rate is nourished and grown, improved in control positive effect; D. according to kind, tree vigo(u)r, using 100～150 times of paclobutrazols controls nourishes and grows.

The invention has the beneficial effects as follows: a kind of method that improves peach fruit-setting rate under Protected Cultivation, for the growth of peach provides suitable growing environment, the generation of preventing disease and pest effectively in advance, improves survival rate, fruit-setting rate and the fruit quality of peach, has good promotional value.

Embodiment

Below in conjunction with embodiment, invention is described further.

Embodiment 1

1. temperature is controlled, and from button canopy is warming up to and blooms, temperature of shed is set to 6 ⁰c～23 ⁰c, guarantees that the vernalization phase was at 45 days, guarantees Pistil And Stamen normal development; Florescence, temperature of shed was for being controlled at 7 to spending latter 8 days ⁰c～22 ⁰c;

2. create suitable pollination condition, to guarantee pollination, fertilization; Every mu of canopy ground discharges the wall honeybee of 500 left and right, and meanwhile, air humidity is controlled at 50%;

3. comprehensive regulation tree vigo(u)r, prevents or alleviates physiological fallen fruit, 1) bud stage, according to tree vigo(u)r, is used 200 times of paclobutrazol integrated control aphids, sticky leaf worm; 2), after bearing fruit, higher due to temperature of shed, humidity, a little less than illumination, Chang Yi causes empty prosperous excessive growth, causes serious physiological fallen fruit, for after preventing from that this phenomenon from occurring, can take following measures: a. to thank spending to stone before the phase, Controlled irrigation amount, not nitrogen fertilizer application; B. carry out in time sublateral shoot pinching; C. thank and spend latter 5 days, 400 times of 15% paclobutrazol of foliage-spray, fruit-setting rate is nourished and grown, improved in control positive effect; D. according to kind, tree vigo(u)r, using 100 times of paclobutrazols controls nourishes and grows.

Embodiment 2

A method for peach under raising Protected Cultivation (middle oily No. 9) fruit-setting rate, its concrete steps are:

1.. temperature is controlled, and from button canopy is warming up to and blooms, temperature of shed remains on 10 ⁰c～20 ⁰between C, guarantee that the vernalization phase is 45 days, to guarantee Pistil And Stamen normal development; Florescence, temperature of shed was controlled at 8 to spending latter 9 days ⁰c～22 ⁰c;

2. create suitable pollination condition, to guarantee pollination, fertilization; Artificial pollination, air humidity during pollination is controlled at 53%;

3. comprehensive regulation tree vigo(u)r, prevents or alleviates physiological fallen fruit, 1) bud stage, according to tree vigo(u)r, is used 150 times of paclobutrazol integrated control aphids, sticky leaf worm; 2), after bearing fruit, higher due to temperature of shed, humidity, a little less than illumination, Chang Yi causes empty prosperous excessive growth, causes serious physiological fallen fruit, for after preventing from that this phenomenon from occurring, can take following measures: a. to thank spending to stone before the phase, Controlled irrigation amount, not nitrogen fertilizer application; B. carry out in time sublateral shoot pinching; C. thank and spend latter 4 days, 350 times of 15% paclobutrazol of foliage-spray, fruit-setting rate is nourished and grown, improved in control positive effect; D. according to kind, tree vigo(u)r, using 120 times of paclobutrazols controls nourishes and grows.
