Abstract
The invention discloses a method of promoting flowering and fructification of an arbor willow in advance. The method of promoting flowering and fructification of the arbor willow in advance comprises the steps that cutting, clip and fertilization are carried out, wicker flower promoting liquid is sprayed on tender shoot stems of the willow every other fifteen days after the midmonth of the January of the next year until the beginning of the March, pinching is carried out on a young shoot, and an upper assistant shoot and a lower assistant shoot are cut out; and wicker fruit retention liquid is sprayed on a flowering branch of the willow every other ten days in the period of fructification until seeds are collected in the midmonth of the April. The method of promoting flowering and fructification of the arbor willow in advance can enable a cutting seedling of the arbor willow to flower and fruit in one year, shortens two years compared with a traditional method, and establishes the foundation for shortening a starting production period of willow fine breeds, improving genetic gain in unit time, researching a heredity judging technology for improving characters of the arbor willow, and accelerating generation research.
Description
Technical field
The present invention relates to a kind of solid method of arbor willow early flowering that promotes.
Background technology
Willow is the general designation of Salicaceae Salix seeds.Salix seeds are very abundant, have in the world more than 500 shrub seeds, for important forest monoid, have important ecology and economic worth.Willow interspecific cross and vegetative propagation are easy, just can blossom and bear fruit but arbor willow cuttage seeding takes 3 years, have affected arbor willow breeding process.
Summary of the invention
The object of the present invention is to provide a kind of the yield positive results solid method of promotion arbor willow early flowering of time of effective shortening.
Technical solution of the present invention is:
Promote the solid method of arbor willow early flowering, it is characterized in that: step is as follows:
(1) cuttings cuttage: mid-February, choose the spray bar without damage by disease and insect from entering breeding time arbor willow, branch is cut into 10-15cm, the cuttings of rugosity 1-1.2cm, again cuttings is immersed to wicker cuttage liquid after 8 hours, by 50cm*60cm seeding row spacing cuttage in whole seed orchard well;
(2) prune: withy is pruned when fine weather in May, the tender tip of tender shoots of the mobile jib lower end 2/3 of erasing, carries out Tipping to mobile jib top, sprays 20ml/L gibberellin after pruning on limb; In the time of July, on arbor willow, spraying every mu of consumption is that 50g is watered the paclobutrazol of 50 kilograms;
(3) fertilising: when cuttings grows into November, be cuttage seeding while being about to fall leaves, carry out single-dose application, fertilizer adopts 15 kilograms every mu of chitin fertilizer ditch spreads;
(4), after Second Year the middle ten days in January, on willow tender shoots stem, sprayed the short flower of wicker liquid every 15 days, until early March, to Tipping, cuts off upper and lower sublateral shoot; Between productive phase, on willow spray, sprayed wicker fruit retention liquid every 10 days, until mid-April sowing.
Described wicker cuttage liquid is made up of metalaxyl 0.003%, the distilled water of disliking mould clever 0.010%, 6-BA 0.002% and surplus.
The described short flower of wicker liquid is the liquid after wicker urgees to spend stoste dilution 1200-1500 doubly, and the short stoste of spending of wicker is made up of the distilled water of 0.002% brassin lactones, 0.001% heteroauxin, 0.003% isopentennyladenine and surplus.
Wicker fruit retention liquid is that wicker fruit retention stoste is diluted the liquid after 1000-1500 times, and wicker fruit retention stoste is made up of the distilled water of 0.06% CPPU, 0.09% gibberellic acid and surplus.
The present invention can impel arbor willow cuttage seeding just can yield positive results in 1 year, at least 2 years are shortened than traditional method, the method, for shortening willow breeding production cycle, improves unit interval genetic gain, improves the Genetic identification technology of arbor willow proterties and accelerates research from generation to generation and lay a good foundation.
Below in conjunction with embodiment, the invention will be further described.
Embodiment
A kind of solid method of arbor willow early flowering that promotes.Its step is as follows:
(1) cuttings cuttage: mid-February, choose robust growth from entering breeding time arbor willow, without damage by disease and insect, accumulation nutriment spray bar, spray nutrient accumulation is at this time the abundantest and will start rudiment, secateurs is become to 10-15cm, the cuttings of rugosity 1-1.2cm.Again cuttings is immersed to wicker cuttage liquid after 8 hours, by 50cm*60cm seeding row spacing cuttage in whole seed orchard well.
(2) prune: withy is pruned when fine weather in May, the erase tender tip of tender shoots of mobile jib lower end 2/3, Tipping is carried out in mobile jib top, suppress leading shoot overgrowing, make vegetation growth of plant change into reproductive nutrition, after pruning, on limb, spray 20ml/L gibberellin, prevent and treat insect pest phenomenon in young sprout growth simultaneously.In the time of July, on arbor willow, spray the paclobutrazol that every mu of 50g is watered 50 kilograms, to suppress tree vigo(u)r apical growth, promote that lateral bud grows.And want at ordinary times timely weeding, draining, irrigation.
(3) fertilising: when cuttings grows into November, be cuttage seeding while being about to fall leaves, carry out single-dose application.Fertilizer adopts 15 kilograms every mu of chitin organic manure (Shandong Huayang agrochemical fertilizer Chemical Co., Ltd. product) ditch spreads.This fertilizer has the required nitrogen of willow, phosphorus, potassium, organic matter, amino acid, protein, trace element etc., contributes to the accumulation of willow nutritive element, promotes the second growth.
(4), after Second Year the middle ten days in January, on willow tender shoots stem, sprayed the short flower of wicker liquid every 15 days, until early March, to Tipping, cuts off upper and lower sublateral shoot.At initial stage mid-March, can grow bud like this, can make the male and female florescence consistent, work is smoothly cross-breeding.Between productive phase, on willow spray, sprayed wicker fruit retention liquid every 10 days, until be sowing at the beginning of mid-April.
Described wicker cuttage liquid is by metalaxyl 0.003%(mass concentration), dislike mould clever 0.010%(mass concentration), 6-BA 0.002%(mass concentration) and the distilled water of surplus form.
The short flower of described wicker liquid is the liquid of the short flower of wicker stoste dilution 1200-1500 after doubly, and the short flower of wicker stoste is by 0.002%(mass concentration) brassin lactones, 0.001%(mass concentration) heteroauxin, 0.003%(mass concentration) distilled water of isopentennyladenine and surplus forms.This short flower liquid has raising photosynthesis, strengthens chlorophyll synthetic, prevents fruit drop, thereby increases fruit quantity raising amount, accelerates the maturation of fruit.
Wicker fruit retention liquid is the liquid of wicker fruit retention stoste dilution 1000-1500 after doubly, and wicker fruit retention stoste is by 0.06%(mass concentration) CPPU, 0.09%(mass concentration) distilled water of gibberellic acid and surplus forms.
This fruit retention liquid has raising photosynthesis, strengthens chlorophyll synthetic, prevents fruit drop, thereby increases fruit quantity raising amount, accelerates the maturation of fruit.
