Background technology
Cherry or cherry have another name called wedge Jing Tao, car li son etc., are the general designations of the plant of some Prunus, comprise cherry subgenus, sour cherry subgenus, laural cherry subgenus etc.Fruit can eat as fruit, bright in colour, sparkling and crystal-clear beauty, red in agate, and Huang is as congealed fat, and nutrition is abundant especially, and fruit is rich in the multiple element such as sugar, protein, vitamin and calcium, iron, phosphorus, potassium.Dalian, the main place of production and Yantai, Shandong.Because cherry maturation time is concentrated, the problem such as then cause sales difficulty, economic benefit not good.Conventional method adopts air-conditioned cold store the fresh-keeping means such as to deposit to delay the selling time of cherry.But so often cause the product phase of cherry, the affected problem of mouthfeel.
Summary of the invention
The object of the invention is to for above problem, a kind of shade net soverlay technique is provided, cherry late variety is regulated and controled, the cherry maturing stage of plantation is stepped back, obtain successfully, thus avoid outdoor cropping cherry listing peak, reach the object of high yield quality benefit.
The invention provides a kind of cherry maturing stage control technique, realize according to the following steps:
1. select cherry variety: (Canada's nineteen fifty-seven is bred as to select husky sweet beans, this kind is improved seeds rare in late variety, three annual bearings, 5 years high yields, strain produces more than 25 kilograms, fruit is individual large, mean fruit weight 12.7 grams, fruit Pi Hongyan, local flavor is splendid, cracking resistance fruit, fruit-setting rate is high, can greatly develop.) etc. late-maturing cherry variety carry out the process delaying the maturing stage;
2. cooling process: comprise shelter from heat or light process and water spray process;
1. shelter from heat or light: cherry adds a cover shade net after bearing fruit above cherry tree;
2. spray water: spray water to reach the effect reducing temperature at noon every day to cherry tree; Spraying frequency is spray once per half an hour, sprays 4 every day; Fountain height is moistening with the cherry tree whole body.
Adopt said method that the maturing stage of cherry can be made to delay more than 25 days.
As another inventive point of the present invention, in cherry cultivation, inventor also investigated the insect-prevention method of cherry:
Described insect-prevention method, specifically refers to the prevention and controls of drosophila larvae, is to be changed to from traditional foliage spray by spray medicine to spray at tree root, thus has stopped fruit bat ovum and enter in cherry fruit, has the problem of drosophila larvae in the cherry solving puzzlement peasant household.
Described spray medicine refers to and known to ordinary skill in the artly drives fruit bat ovum medicine.But preferably chlorophos or avermectin.
Beneficial effect of the present invention is: delayed the maturation time of cherry, has stopped fruit bat ovum and has entered in cherry fruit, has the problem of drosophila larvae in the cherry solving puzzlement peasant household.
Embodiment
Sweet for sand beans cherry tree is added a cover shade net after bearing fruit above cherry tree; Spray water to reach the effect reducing temperature at noon every day to cherry tree; Spraying frequency is spray once per half an hour, sprays 4 every day; Fountain height is moistening with the cherry tree whole body; Spray at cherry tree root place after the chlorophos of 80vt% is diluted 1000 times, thus stopped fruit bat ovum and enter in cherry fruit, in the cherry solving puzzlement peasant household, have the problem of drosophila larvae.Adopt said method that the maturing stage of cherry can be made to delay more than 25 days.
The above embodiment; just preferred embodiments of the present invention; and unrestricted the scope of the present invention, therefore all equivalences done according to the material composition described in the present patent application the scope of the claims, making characteristic sum principle change or modify, and all should be included in patent application protection domain of the present invention.
