Description

A kind of red date bag and using method thereof

Technical field

The present invention relates to bagging and bagging method that a kind of fruit trees during growth period uses, be specially a kind of bagging that the red date process of growth uses and using method of this bagging of being used for.

Background technology

The regular period of fruit growing, adopt bagging mode worker, can reduce fruit and encroached on by the disease worm, also can avoid fruit directly to contact with agricultural chemicals, guarantee fruit quality.The available technology adopting fruit bagging mainly contain pears, the Pingguo, grape etc., because pears and Pingguo are single fruit, its cover bag constructions is also comparatively simple, usually adopt a rectangle paper bag, there is running-on on one side at paper bag, side has ventilation mouth, from running-on one side fruit is put during use, get final product with rope or thin wire tighten, the weak point of this cover bag constructions is that running-on one side is a straight structure, the tying place shrinks more during use, significantly reduced usage space in the cover,, increased the inner bag space if will change this situation, just bagging must be increased, this will increase cost.When another defective of this bagging is to use, do not support, make the inwall of bag when being infected with dew in wet in the bag water or the bag be close to and no longer separate when raining, can influence fruit growth with fruit because bag is interior.

Grape is the fruit of bunchiness growth, adopts the cover bag technique later, and its cover bag constructions and pears, Pingguo etc. are similar, and existing grape bagging has also increased in running-on one side ties up silk, during use, ties up silk and fixes with branch.As Chinese patent 02274361.8 disclosed a kind of " grape growth phase bagging ", the binding fixed strip that it comprises bagging and is fixed on bagging one side is respectively equipped with the draining air-vent in the both sides, lower end of bagging.Chinese patent 01240524.3 disclosed a kind of " Grape protection bag " adopts inner bag and outer bag to constitute, and inner bag toughness is ventilative, and outer bag is soft to ventilate.Chinese patent 200820013855.8 disclosed a kind of " grape fruit ear bagging with fruit bag " adopts PEF paper to make, and air vent is arranged at the bottom of bag, bagging is bundled in the bar of tying up on the branch being useful on the sack.

Though above-mentioned fruit bag is obtained good result, this technology can not be used on red date, and red date bag at first will guarantee to have in the bag enough spaces, and next requires bagging back pkt. shape that certain support is arranged, and the red date in the growth is not contacted with the inwall of bag as far as possible.Because red date is afraid of fruit surface and water Long contact time most in the later stage of growth, in case of rain or bag in condense dew, when the inwall of bag got wet and is close to the surface of red date, red date can absorb large quantity of moisture, causes dehiscent fruit, has a strong impact on its quality.Therefore, though fruit bag has become the comparatively general technology of a kind of northern area, on red date, there is not to propose suitable bagging method so far.At the problem that prior art exists, the someone has invented a kind of mocromembrane bagging, adopts adipose membrane emulsion to convert water and evenly is sprayed at jujube fruit face, guarantees that jujube really sprays fully.Along with jujube really expands, not timing sprays this agent in the fruit face then.This red date surface that repeatedly chemical emulsion is sprayed at also hides the blade face simultaneously, influences photosynthesis.In addition, red date is in vegetative period in the chemical emulsion parcel always, even this emulsion can not form hazard residue, but people still can produce psychological uneasiness when edible.

Summary of the invention

The present invention is directed to red growth characteristics, designed a kind of red date bag, solved existing fruit bag tying place and shunk too much, caused that bag interior space is little does not have support with bag, meet that water is easily collapsed and bag inside water problem such as can't discharge, the present invention has also disclosed the using method of this red date bag.

A kind of red date bag of the present invention and using method thereof, comprise a bag that constitutes by two paper, opening is arranged on the bag, it is characterized in that described opening is positioned at the bag two ends, wherein an end opening is that jujube hangs or the branch inlet, other end opening is that jujube hangs or the branch outlet, is fixed with in the bag both sides and ties up bar;

Using method:

1. after the red date first phase, setting was finished, spraying fungicide came off the later stage flower;

2. select setting preferably jujube hang one to three or whole branches and be inserted in the bag from an end opening, jujube hangs or the end of branch is stretched out by the other end opening of bag, with tying up bar with both ends open colligation respectively;

3. the end opening adjusting bag and make bag down.

Described a kind of red date bag and using method thereof, wherein the both ends open on the bag is V-arrangement opening or U-shaped opening.

Described a kind of red date bag and using method thereof is characterized in that there is the support edge in the outside of tying up bar, in the outside, support edge little opening are arranged.

Described a kind of red date bag and using method thereof, bactericide wherein are Tebuconazole.

Described a kind of red date bag and using method thereof, the sprinkling number of times of wherein said fungicide tebuconazole are to be the blanking time of one to twice, twice sprinkling two to three days.

A kind of red date bag of the present invention and using method thereof, adopt parchment to make the waterproof paper bag, red date is hung or branch is inserted in, the assurance red date can be infected with agricultural chemicals in process of growth, particularly red date is grown the later stage, prevent that rainwater from contacting for a long time with red date, effectively stopped the dehiscent fruit phenomenon of raining and causing.Can prevent also that simultaneously damp and hot damp vapour from contacting with red date, cause certain kind of berries fungus diseases to take place.V-arrangement opening or U-shaped opening are left in the paper bag two ends, are convenient to that jujube hangs or branch is inserted in and the branch end stretches out the bag outside, are beneficial to the red date growth.Discharge with tying up the small amount of moisture that the opening that forms naturally after the bar colligation conveniently enters in the bag.The method according to this invention is carried out bagging operation, confirms through 2 years field experiments, can prolong about 20 days breeding times through the red date of bagging, has stopped the generation of sick worm harm and dehiscent fruit substantially, and fruit and agricultural chemicals do not come in contact, and guarantee the fruit non agricultural chemical residuum.For the control efficiency of a large amount of brown spot, anthracnose and dehiscent fruit phenomenons that take place reaches more than 90% in China jujube garden in recent years.The red date pericarp is natural bright and clean, and outward appearance is beautiful, and maturity significantly improves, good mouthfeel, and the red date quality can superior matter standard, and commodity value gets a promotion.
