Description

Pruning rejuvenation method of low mountain hill eggplant in south

Technical field

The present invention relates to the culture technique of a kind of vegetables, especially be applicable to southern low mountains and hills area eggplant pruning rejuvenation method.

Background technology

Eggplant (Solanum melongena L) is the main vegetable crop type of China, reveals that to plant area big spring, the output height, and concentrate picking time, and 7-8 month in the full bearing period is because of concentrating listing, high yield low price phenomenon ubiquity.The characteristic of utilizing eggplant side shoot axillalry bud to sprout easily in the production before and after the beginning of autumn, according to various places vegetables market supply situation, is selected suitable period, by reasonable pruning rejuvenation, promotes old branch regeneration, avoids summer high temperature and listing peak, to improve the eggplant productivity effect.In the practice, because kind, weather conditions are different with planting type, each common pratia fruit beta pruning time, beta pruning position and method divergence are very big.South open country eggplant production tradition pruning method is that eggplant is gathered and finished the back keep 3 side shoots more than plant first branch, stays the 8cm snag after cutting; Northern area utilizes facility cultivation to realize regeneration in the beta pruning of the liftoff 10cm of plant mobile jib place.Adopt the plant of above-mentioned pruning method to recover slower, the update cycle is long.The shoot result needs more than 40 day, therefore is difficult to promote.

By retrieval and the investigation, do not see the eggplant that spring, dew was planted as yet and entering the beta pruning renewal of octahedral wind fruit growth middle and later periods, and after beta pruning, gathered with interior realization in 25 days, be fit to the report and the practice of the eggplant pruning rejuvenation technology of southern low mountains and hills area open country in spring plantation again.

Summary of the invention

At long deficiency of eggplant tradition beta pruning update cycle, the technical problem to be solved in the present invention provide a kind ofly be suitable for southern height above sea level 200-400 rice low mountains and hills common pratia fruit outdoor cropping in spring environment, simple and flexible, restoration result is fast, the plant growing way is good, the mountain region eggplant pruning rejuvenation method of the listing supply of avoiding the peak hour.

The technical scheme that solves the problems of the technologies described above is: this southern low mountains and hills common pratia fruit pruning rejuvenation method is taked following measure:

(1) select time of beta pruning: the middle ten days and the last ten days in annual July, before fine at 10 o'clock in the morning or carry out after at 4 o'clock in afternoon;

(2) select weather and eggplant vegetative period of beta pruning: local climate changes the phase first day of the first period of the hot season over to, and plant enters the middle and later periods of octahedral wind fruit growth and carries out;

(3) position of beta pruning and concrete operations: wipe out four female bucket position one-level or secondary side shoots, forward is sheared, and clip should be put down, and stays snag 3-5cm, or the clip waxing, stays snag 2-3cm;

(4) cut the back management: the eggplant field keeps moistening, soil moisture content 30%-40%, cutting the 2-3 days plant axillalry buds in back occurs sprouting and promptly begins spraying medicament, prevention and elimination of disease and pests 2-3 time, cut the back 5-7 days, when young sprout grew to 8-12cm, each kept 1-2 healthy and strong young sprout, the unnecessary young sprout of erasing changes Routine Management later on over to.

The invention has the beneficial effects as follows at the high temperature season that will enter the hottest period of the summer, eggplant is carried out pruning rejuvenation, neither influence the preceding output of beta pruning, can quicken old branch regeneration again, shorten the update cycle, realize receiving for one batch two and increase gross yield and the supply of material peak listing supply of staggering in time, eggplant economic benefit height, market equilibrium supply.

Embodiment

The present invention is described in further detail below in conjunction with embodiment: well-known, the factor that influences eggplant pruning rejuvenation effect is a lot, as the management after cultural area, environmental condition, beta pruning period, beta pruning position, method of operating and the beta pruning etc.Therefore, it should be noted that southern mountain that this method is applicable to open country plantation in spring is especially with the low mountains and hills common pratia fruit of height above sea level 200-400 rice, the applicant's proving ground is just at the height above sea level 215 of the northwestward, Zhejiang and the place, low mountain of 360m, based on this, it is the middle ten days and the last ten days in July that this method is selected the time of beta pruning, the characteristic that tangible area and height above sea level are arranged, for the benefit of with reference to promoting again the selection in vegetative period of openly weather and eggplant, the various places beta pruning time can suitably be adjusted by local actual the work.

This method is to carry out on the basis of Routine Management in early stage, and this is no longer carefully stated, and beta pruning enters octahedral wind (industry slang, i.e. fruit growth middle and later periods) with plant strain growth period, and local weather changes over to is advisable the period first day of the first period of the hot season.Beta pruning is too early, influences the accumulation of mountain region eggplant early yield and plant nutrition; Beta pruning is slow excessively, can cause plant to upgrade evening, influences pruning rejuvenation effect and product quality and benefit.

Beta pruning was selected in before at 10 in the fine morning or carries out after at 4 in afternoon, and this is that to lose liquid too much for wound under the noon burning sun because the rainy day is unfavorable to wound healing.Select four door sockets (also to claim four female buckets, be eggplant plant strain growth mid-term) first or second level side shoot beta pruning, forward is sheared, otch is flat, should not cut sth. askew, and the diffusing greatly liquid of the tangent plane of cutting sth. askew is many, need stay snag 3-5cm when cutting, available wax with good conditionsi is coated with the envelope clip, then stays snag 2-3cm, does not influence axillary bud sprouting when staying the favourable stubble of snag withered and takes out the tip.

Cut the back and keep the eggplant field moistening, soil moisture content is controlled at 30%-40%.Should strengthen the management of prevention and elimination of disease and pests to cutting new blade face slightly, back, occur sprouting, in time can kill to such an extent that 600 times of liquid or 50% speed can be sprayed 2-3 time by clever 1500 times of liquid with 500 times of liquid of 50% carbendazim or 77% from cutting the 2-3 days plant axillalry buds in back; Cut the back 5-7 days, when newly growing to the 10cm left and right sides slightly, each keeps 1-2 healthy and strong young sprout, the unnecessary young sprout of erasing.Change Routine Management later on over to.

This method was chosen in for four door socket periods to the in good time beta pruning of the proper site of I and II side shoot, helped guaranteeing output and quality before and after the beta pruning.By upgrading rejuvenation, realize summer high temperature retarding of growing in season, listing of wrong season (peak) realizes high quality and favourable price, improves more than 7000 yuan/mu than conventional cultivation benefit (local present price).
