The breeding method of the new quality of peach
Technical field
The present invention relates to agrotechnique, be specifically related to the breeding method of the new quality of peach.
Background technology
At present, the area of China except the north all do not have the peach variety that can go on the market in the winter time.The consumer in area except the north if think to eat in the winter time peach, must allocate and transport from the north.Because the area beyond the north to the north, the especially north are far away to south; In the transportation, the unavoidable extruding of peach is burst disorderly, through long-distance transport to southern winter peach often product differ the influence sale.In addition, long transit link expends time in longer, and stale to dealer winter peach on hand again from orchard worker to forwarding agent, mouthfeel is relatively poor.Thereby the winter peach in the north does not often have market in south, south in the winter time, especially the present situation of not having a peach in season severe winter can not get improving.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide and to improve the north regional present situation of not having peach season severe winter in addition, satisfy consumer demand, the breeding method of the new quality of peach of quality better.
To achieve these goals, the technical solution used in the present invention is:
The breeding method of these peach new varieties is specially:
(1) at the field ridging, at the ridge upper seeding wheel;
(2) behind the kind eclampsia gravidarum bud, regularly water and apply fertilizer, carry out routine and arrange;
(3) the peach seedling was cultivated after 1 year, got the new twig of Chinese peach offered as a birthday present as scion, was that stock carries out grafting with the peach seedling, and scion is whittled into blade-like, is plugged in wooden part or bast and the wooden handing-over position of stock;
(4) with plastic film the grafting mouth is wrapped up, expose scion and breathe, treat to remove film after the scion growth survives;
(5) after the grafting in the peach process of growth, when the field temperature is higher than 35 ℃, between the ridge of peach growth and ridge, evenly spread one deck grass, prevent the high temperature peach seedling of burning;
(6) in peach before the florescence 5~7 days, take booth in the peach periphery in field, all peach are placed in the formed confined space of booth, reduce temperature of shed and with temperature of shed control at 2~5 ℃, continue after 60 days, the rising temperature of shed makes temperature of shed continue to rise to normal temperature, the booth of dismantling;
(7) regularly water and apply fertilizer to peach, carry out routine and arrange.
During the field ridging, the ridging height is 70~80cm, and spacing is 50~60cm between the ridge.
The peach variety as stock of sowing is wild peach or nectarine.
Littering thickness between on the ridge and ridge is more than the 10cm.
The invention has the advantages that: the breeding method of these peach new varieties, grafting China peach offered as a birthday present on the peach seedling that cultivate in area beyond the north, as required, when temperature is too high, take the method for anti-high temperature sintering grafting peach seedling, guarantee the normal growth of grafting peach seedling, the method of taking peach to lower the temperature before the florescence and handle is postponed the florescence that peach blooms; The new quality of peach that forms after this China's peach offered as a birthday present grafting can not only adapt to the demand of area growth beyond the north, and ripe by the end of January, reaches mutually at product to be better than the winter peach that grows in the north more aspect the quality; Especially under the weather conditions of south and the central and east, these peach new varieties of plantation, sugar is higher, and mouthfeel is fabulous.The breeding method of these peach new varieties, really with the winter peach be introduced into the area that the north is thought, improved regional winter, especially season severe winter thought in the north and do not had the situation of peach, satisfied consumer demand.
Embodiment
Description below by to optimum embodiment is described in further detail the specific embodiment of the present invention.
The breeding method of these peach new varieties is specially:
(1) at the field ridging, the ridging height is 70~80cm, and spacing is 50~60cm between the ridge, at ridge upper seeding wheel wild peach or nectarine seed;
(2) behind the kind eclampsia gravidarum bud, regularly water and apply fertilizer, carry out routine and arrange;
(3) the peach seedling was cultivated after 1 year, got the new twig of Chinese peach offered as a birthday present as scion, was that stock carries out grafting with the peach seedling, and scion is whittled into blade-like, is plugged in wooden part or bast and the wooden handing-over position of stock;
(4) with plastic film the grafting mouth is wrapped up, expose scion and breathe, treat to remove film after the scion growth survives;
(5) after the grafting in the peach process of growth, when the field temperature is higher than 35 ℃, between the ridge of peach growth and ridge, evenly spread the grass more than one deck 10cm, prevent the high temperature peach seedling of burning;
(6) in peach before the florescence 5~7 days, take booth in the peach periphery in field, all peach are placed in the formed confined space of booth, reduce temperature of shed and with temperature of shed control at 2~5 ℃, continue after 60 days, the rising temperature of shed makes temperature of shed continue to rise to normal temperature, the booth of dismantling;
(7) regularly give peach water and fertilising, carry out routine and arrange.
Situation according to regional rainy water beyond the north, at the ridge upper seeding wheel, the ridging height is 70~80cm, and spacing is 50~60cm between the ridge, on the one hand can satisfy the growth demand that the peach seedling is not liked water, ridge high energy satisfies and waters, applies fertilizer and actual production demand such as harvesting on the other hand.
In the stock process of growth, when the field temperature is higher than 35 ℃, between the ridge of peach seedling growth and ridge, spread the grass more than the 10cm; Grass can provide protection for peach, and when preventing sun direct projection ground, surface temperature is too high to damage the peach root, effectively prevents the high temperature peach of burning, and guarantees the area growth that this peach new product mass-energy is thought in the north.
In peach before the florescence 5~7 days, all peach are placed in the formed confined space of booth, in booth, place refrigerator, adopt refrigerator to reduce temperature of shed and with temperature of shed control at 2~5 ℃, continue after 60 days; Remove refrigerator in the canopy gradually, rising temperature of shed slowly makes temperature of shed continue to rise to normal temperature, the booth of dismantling then; The method of taking peach to lower the temperature before the florescence and handle is like this postponed the florescence that peach blooms, and makes peach ripe by the end of January, improves the situation that south does not have peach season severe winter.
Above the present invention has been carried out exemplary description; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
