Abstract

The invention discloses a winter jujube abscission preventing method. The winter jujube abscission preventing method comprises the following steps of (1) selecting high-quality varieties; (2) strengthening summer management; (3) strengthening water and fertilizer management; (4) delaying shell breaking; (5) strengthening management of a fruitlet expanding period; (6) performing timely chemical prevention. By means of comprehensive measures, the stress resistance of plants can be strengthened. The winter jujube abscission preventing method is simple and high in operability, improves the fruit setting rate of the plant, effectively prevents abscission of winter jujube, increases both production and income, improves the quality of fruit and accordingly improves the economic benefits, and is particularly applicable to abscission prevention of the winter jujube.

Description

A kind of method of preventing and treating of winter jujube shedding

Technical field

The present invention relates to the management method of fruit tree, be specifically related to a kind of method of preventing and treating of winter jujube shedding.

Background technology

Winter jujube, also claims winter jujube on good fortune on mausoleum, apple jujube, rock sugar jujube, Shanxi winter jujube, mausoleum, is the late-maturing kind of eating raw of a high-quality of North China.Winter zizyphus is in Rhamnaceae, zizyphus.The late-maturing improved seeds of eating raw of stingless jujube tree.Miao Shang township, Yuncheng, original producton location, existing a large amount of planting sites are distributed in Shanxi, Hebei, Shandong, Shaanxi, Xinjiang, etc. ground.The thin meat of its pericarp is thicker, delicate succulence, chew without slag, dense sweet micro-acid, samples splendidly, should eat raw, vitamin content is 70 times of apple, 100 times of pears, vegetal pole horn of plenty, is described as " vitamin pill of living ".

Shedding is the one performance of plant to environmental suitability reaction, it is the common phenomenon in winter jujube cultivation, normal physiology comes off not only harmless but also useful, came off and spent more and young fruit, left fruit will have more sufficient nutriment to supply with, can form larger fruit, be conducive to improve the yield and quality.But, if flowers and fruits come off too much, certainly will reduce output, affect orchard worker's income, become and produce a upper major issue that must solve.The phenomenon of winter jujube shedding is comparatively general sees, mainly contain physiological fruit drop, trace it to its cause, the first, early July, young sprout growth before this, root growth, blooming and bearing fruit all needed to consume the nutrition of a large amount of tree body on the occasion of the tree body nutrient competition phase, branch, leaf, root, really asked the dog-eat-dog of nutrient, nutrient distribution is unbalanced, can cause a large amount of sheddings; In addition, tree body is weak, storage oligotrophy, flower bud differentiation is of poor quality, causes shedding.Therefore, need to provide effectively preventing method to winter jujube shedding phenomenon.

Summary of the invention

For the problems referred to above, the invention provides a kind of method of preventing and treating of winter jujube shedding, the method can improve the resistance of winter jujube, effectively prevents and treats shedding, increases the quality of output, raising fruit.

For achieving the above object, the technical solution used in the present invention is:

The method of preventing and treating of winter jujube shedding, comprises following measures:

(1) kind is selected: the winter jujube kind of selecting high-quality, applicable local plantation and strong stress resistance;

(2) strengthen summer management: at early and middle ten days in May, erase and there is no the jujube head sprouted on the skeleton branch of growing space, remove jujube head on jujube thigh and stay the rudiment while hanging, extract the heart of jujube head branch and Secondary Branch, the nutrient competition causing to reduce too much shoot growth;

(3) strengthen rich water quality management: in late May, plant is watered, and in conjunction with using urea, consumption is 0.5kg/ strain, sprayed 1 time 0.3% potassium dihydrogen phosphate aqueous solution in every 15 days of June, sprayed 1 time 0.3% aqueous solution of urea in every 10 days of July, sprayed 0.3% potassium dihydrogen phosphate aqueous solution 1 time in every 10 days of August, to increase the accumulation of tree body nutrition;

(4) postpone to open first: at jujube tree full-bloom stage in June, open first 60% time the flowers are in blossom, band girdle width is 0.5～1cm, and every strain tree opens 3～5 first mouths, and position is chosen on skeleton branch, and will stay auxiliary support branch;

(5) strengthen the management of young fruit expanding stage: at early July young fruit expanding stage, plant is sprayed to the methyl α-naphthyl acetate of 20mL and the mixed liquor of 0.3% potassium dihydrogen phosphate, can promote Fruit, reduce shedding;

(6) in time chemical control: by the end of June to the winter jujube tree spray the protective fungicide that suddenly kills agent water dispersible granules; 7,8, sprayed one time protective fungicide every 15 to 20 days September, alternately sprays 800 times of liquid of 90% carbendazim water dispersing granule and 800 times of liquid of 70% thioneb wettable powder.

As optimal technical scheme, for the supply fruit that ensures that plant has enough nutrition relatively to concentrate, thereby ensure fruit-setting rate, when opening first, plant sprays 15mg/L gibberellin and 0.3% borax soln.

The invention has the beneficial effects as follows: strengthened the resistance of plant self by selecting fine quality, strengthen summer management and strengthening rich water quality management; Postpone to open first, strengthen the management of young fruit expanding stage, improved the fruit-setting rate of plant, thus control winter jujube shedding; Chemical control has in time ensured last defence line; The method of preventing and treating is simple, strong operability, the shedding phenomenon of effectively having prevented and treated winter jujube, and increasing both production and income, has improved the quality of fruit, thereby increases economic well-being of workers and staff.

Embodiment

Below in conjunction with specific embodiment, the present invention is further described.

Embodiment 1

The cultivation method of the present embodiment jujube tree in spring comprises the following steps:

(1) kind is selected: select to be applicable to local jujube kind high-quality winter, jujube northern Shandong winter, strong stress resistance;
