Abstract

The invention discloses application of light conversion films in greenhouse tea planting. A tea plantation is covered by the light conversion films, starting-to-pick time can be brought forward by more than 10 days compared with that of outdoor tea plantations, and calculating according to that 5 kilograms of brand-name and high-quality green tea are produced per mu, during the advanced in-the-market period, selling price per kilogram can be increased by more than 1000 yuan, so that income increase per mu exceeds 5000 yuan. Due to changes of light quality, spring tea can be brought into market more early, inherent quality of the tea is improved, the image that greenhouse tea needs to be picked as soon as possible and does not taste good is changed, market competitiveness is improved, and social benefit is obvious.

Description

The application of conversion film in the plantation of booth tea

Technical field

The invention belongs to the Tea planting technical field.

Background technology

Greenhouse cultivation tealeaves is one of important culture technique that early spring, well-known tea went on the market in advance.Although the booth tea quality of listing has been catered to the consumer and had a taste of what is just in season, tastes psychology early not as open-air spring tea ahead of time, and is in demand, high efficiency.

The cladding material in tradition booth tea place is generally plastic film for agricultural use ageing-resistant, that nothing is dripped dustproof and heat insulation function, the principle that tealeaves is exploited in advance is, temperature of shed is higher than ambient temperature after the solar radiation, the effective accumulated temperature in the canopy that raise, thus tea tree is sprouted ahead of time.

Along with the decline of air quality and the abnormality of weather condition, haze weather is more and more but in recent years.Have a strong impact on daylighting and the intensification in booth tea place, caused the canopy internal-external temperature difference to dwindle.Take Hilly area of Jiangsu Province booth tea place as example, nearest 3 years, the more open-air tea listing in booth tea place can only be done sth. in advance about a week.Because the more open-air tea of quality of booth tea is poor, and its market favor degree is received strike, the advantage in booth tea place weakens in addition.

Summary of the invention

Technical problem to be solved by this invention provides the application of conversion film in the plantation of booth tea, to improve the quality of booth tealeaves.

For solving the problems of the technologies described above, technical scheme of the present invention is as follows:

The application of conversion film in the plantation of booth tea.

Visible light part is the light source (360-760nm) that Growth of Tea Plants has the greatest impact, and what the absorption of tea tree chlorophyll was maximum is red, orange light, secondly is blue, purple light.

Red, gold-tinted can promote the formation of growth of tea plant growth and carbohydrate; Royal purple light then is beneficial to protein and amino acid whose formation, and with the direct relation that is formed with of some nitrogenous quality components such as vitamin and a lot of fragrance components.The luminous energy of the above wavelength of 700nm almost is the unavailable invalid radiation of tea tree entirely, but can be used as the thermal source that environment heats, and improves the effective accumulated temperature in the booth tea place.

Conversion film adds the canopy film of making after " turning the exhibiting optical function masterbatch " exactly in the raw material of producing common canopy film.When sunlight sees through " conversion film ", ultraviolet ray in the sunlight and green glow etc. are harmful to or useless light wave, " light conversion matrix materiel " in the tunicle absorbs conversion, discharge royal purple light and the ruddiness favourable to plant growth, to improve the utility rate of luminous energy of crop in the canopy, exploit in advance and put forward high-quality purpose thereby reach.

Concrete application method is:

(1) booth design: the tea place gradient is no more than 10 degree, and length 60-80 rice is advisable, 6 meters of width, and 2.5 meters of height are built with tube material.

(2) the booth tea garden soil is improved and is fostered and apply fertilizer: require to plough deeply the tea place in August, and 9-10 month, drop into fertilizer (pig manure, tangerine bar, colza cake mix) 150kg/ mu, composite fertilizer 20kg/ mu is improved soil.

(3) plastic house: water before the covering permeable 1 time, replace common nothing to drip film with conversion film and cover booth, Best Times is between 20-December 5 November, should not be excessively slow.

(4) Temperature and Humidity Control in the booth: according to tea shoot growing state control temperature, general control is between 30-35 degree centigrade; Humidity is controlled about 70-90%.

(5) carry out the work such as windproof, snow, fire.

Beneficial effect: the present invention covers the tea place with conversion film, and the in advance exploitation more than 10 days of comparable open-air tea place is produced 5 kilograms of famous green teas with every mu and calculated, and during the listing, the per kilogram price can improve more than 1000 yuan, per mu increasing income above 5000 yuan in advance.Simultaneously because the change of light quality in ahead of time spring tea listing, improves its interior quality, changed the image of booth tea original " as early as possible, bad drinking ", strengthen the competitiveness in market, social benefit is remarkable.

Embodiment

According to following embodiment, the present invention may be better understood.Yet, those skilled in the art will readily understand, the described content of embodiment only is used for explanation the present invention, and should also can not limit the present invention described in detail in claims.

Embodiment 1:

(5) carry out the work such as windproof, snow, fire.

Claims

1. the application of conversion film in the plantation of booth tea.

2. application according to claim 1 is characterized in that, application method is:

(1) booth design: the tea place gradient is no more than 10 degree, length 60-80 rice, and 6 meters of width, 2.5 meters of height are built with tube material;

(2) booth tea garden soil improvement with foster and apply fertilizer: plough deeply the tea place August, drop into fertilizer 150kg/ mu 9-10 month, composite fertilizer's 20kg/ mu is improved soil;

(3) plastic house: water before the covering permeable 1 time, replace common nothing to drip film with conversion film and cover booth, the time is 20-December 5 November, should not be excessively slow;

(4) Temperature and Humidity Control in the booth: according to tea shoot growing state control temperature, general control is between 30-35 degree centigrade; Humidity is controlled 70-90%;
