Abstract

A fruit tree cover is characterized in that a fruit tree crown is covered with a layer of nylon net cover; and the periphery of a net is tied with one end of each of 4 to 6 ropes, and the other end of each rope is fixed on the ground, a rod piece or a tree trunk respectively. Due to the adoption of the fruit tree cover provided by the utility model, the pest and disease perniciousness can be greatly reduced, and the fruit tree cover is better than a plastic-covered tunnel or a greenhouse in conditions such as soil, CO2, lighting and the like, so that the ecological environment of the fruit tree is improved. Furthermore, the fruit tree cover has the advantages of simple management and easy manufacture and is very favorable for popularization.

Description

The fruit tree cover

Technical field

The utility model belongs to the fruit tree cover that planting fruit trees is used.

Background technology

Fruit tree occupies critical role in national economy.The strategy that China long-term implementation fruit tree goes up a hill down the beach, do not strive ground with grain and cotton; overwhelming majority fruit tree does not have facilities protection; the ability of withstanding natural calamities is very weak; for example sick worm harm; the a large amount of agricultural chemicals of not only annual consumption; the expense of administering insect pest is one of prime cost of orchard expenditure, and directly threatens food security, influences people's health.In addition, fruit growth period is met heavy rain and is caused dehiscent fruit, is exposed to the sun to cause and burns fruit day, burn limb day, brings massive losses all can for the fruit industry.

The mankind cultivate apple trees the technology of protection very early.Beginning in 19 end of the centurys, states such as Belgium, Holland utilize the glass greenhouse cultivating grape in vogue already.Along with the development of automated control technology, the improvement of Gardening Materials and the development of fruit growing intensification, the area under cultivation of countries in the world protected fruit trees progressively increases.The fruit tree that facility cultivation is carried out in present countries in the world has reached 35 kinds more than.The fruit tree facility cultivation of China starts from the 1950's, but to the grape plastic film solar greenhouse cultivation seventies, just success successively of plastic tunnel test plantation, fruit tree plastic membrane booth and greenhouse culture afterwards progressively promoted.In recent years, along with the development of dull season fruit and the short close culture technique of fruit tree, the existing very great development of China's fruit tree facility cultivation.

At present, the key facility type of China fruit tree facility cultivation has:

(1) minimum facility

The area of heavy rainfull, south is many to be covered with rain-proof shelter or surface, and the form of rain-proof shelter mostly is and covers polyethylene film on support, is equipped with shade net, in order to take shelter from rain, cooling, diseases prevention, winter protection, frost prevention, windproof, anti-bird and prevent erosion etc.; Canopy face cladding material is in the majority with polyvinyl alcohol, polyethylene fibre, polypropylene film.

(2) senior facility:

Following form is generally arranged:

Plastic tunnel: plastic tunnel is built easy, easy to use, small investment, in the northern area of China, can make general spring 30～35d, autumn can delay 20～25d in advance fruit phase; And in south, except winter-spring season insulation and the cultivation that is used for fruit tree, summer and autumn also can be by changing shade net realize sheltering from heat or light cooling, rainproof, windproof and hail suppression etc.

Plastic film solar greenhouse: the preceding domatic employing plastic foil in single domatic greenhouse; Can make full use of that daylight heats, good leak tightness, heat radiation less, high insulating effect, be convenient to the control of ecological factor and lower, the energy savings of investment.

The traditional glass greenhouse by solar heat: light transmission and heat insulating ability are better than plastic film solar greenhouse, though cost of investment is higher, more help the regulation and control to the fruit tree ecological factor, have better cultivation effect, and facility are firm, and service time is long.If warming-up device is arranged, benefit is better in the greenhouse.This greenhouse is used for the colder area of northern China more.

Though the cultivation of China fruit tree facilities protection has obtained tremendous development, owing to multiple reason, that adopts facilities protection only accounts for the fruit tree gross area about 0.53%.Further simplifying the fruit tree facility, realize low cost and practical, is the only way of impelling fruit growing to top bar.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of simplification fruit tree facility, reduction facility cost, easy to use, the significant fruit tree cover of effect.

The utility model solves the problems of the technologies described above with following technical scheme:

On top fruit sprayer, cover a nylon guard, an end of 4-6 bar rope hitch respectively net around, the other end of rope is separately fixed on the ground or on the rod member or on the trunk.

Use fruit tree umbrella of the present utility model, outstanding advantage is:

1. after top fruit sprayer is covered, can significantly reduce the harm of disease worm, reduce spray medicine cost, produce nuisanceless fruit.

2. improved the ecotope of fruit tree, can keep out wind and rain, sun-proof cold-resistant, alleviate bright, rainy dehiscent fruit of fruit fruit day phase.

3.. totally-enclosed because of not having, soil, CO ₂, condition such as illumination is better than plastic tunnel or greenhouse, management is simple.

4. easy to manufacture, very be beneficial to popularization.

Description of drawings

Fig. 1 is the structural representation of the utility model fruit tree cover.Among the figure fixedly the other end of 4 of nylon guard ropes be separately fixed on two rod members 4.

Embodiment

When the scheme that adopts as shown in Figure 1, an end that has covered 2, four ropes 3 of a nylon guard on the top fruit sprayer 1 hitch respectively guard around, the other end of every relative two ropes is tied up the two ends at same rod spare respectively.

Because the nylon guard will have the function of insect-pest, so the nylon wire that the nylon guard should be chosen about 40 orders is made.

Drawing materials extensively of rod member can use rod, bamboo bar or branch to make.

In actual application, the rod member that rope is being tied up at two two ends can not be connected with trunk, and each rod member is in free state.If the restriction rod member is free movable, then can be held together with the middle part and the trunk of rope with rod member; Along with growing tall of fruit tree, the position of tie point up moved get final product.

Fruit tree cover of the present utility model is a unit with the isolated tree, has utilized tree crown of fruit tree and trunk to make; Do not have totally-enclosedly under the cover, saved the nylon wire materials; And utilize stay cord to fix, saved overall materials.

Claims (1)

1. a planting fruit-trees cover is characterized in that covering a nylon guard on top fruit sprayer, an end of 4-6 bar rope hitch respectively net around, the other end of rope is separately fixed on the ground or on the rod member or on the trunk.
