Problems solved by technology

[0008] In short, the existing technology has the following defects: (1) The time for fruit trees to be released from dormancy is late, which makes it difficult to advance the fruit ripening time, and the economic benefits are not ideal; (2) Using high-power refrigeration equipment can make the fruit ripen earlier, but consumes electricity The cost increases, and the increased cost is not directly proportional to the increased benefit; (3) The thermal radiation blocking rate of the existing film is low, and it is difficult to effectively control the internal temperature of the facility; (4) The inability to break through the need for more cooling makes it difficult to plant in the north and south main reason for success

Embodiment 1

[0046] Embodiment 1 A kind of method of releasing dormancy of deciduous fruit trees early

[0047] Cover the solar greenhouse for planting deciduous fruit trees with astigmatism cooling and thermal radiation control film, and send air-conditioning or cold water mist into the greenhouse to control the temperature. .

[0048] The experiment was carried out at the Hanting Experimental Base of Weifang Academy of Agricultural Sciences, and two greenhouses (Greenhouse 1 and Greenhouse 2) were selected. In each of the Greenhouses 1 and 2, 60 'Longfeng' peach trees with a tree age of 3 years were planted.

[0049] Greenhouse 1: implement according to the method of the present invention throughout the growing season in 2013; concrete steps are as follows:

[0050] Step 1 Greenhouse preparation

[0051] In October, on the solar greenhouse, from the inside to the outside, prepare ordinary greenhouse film, thermal insulation quilt, astigmatism cooling thermal radiation control film; cov...

[0085] Example 2 A special astigmatism cooling thermal radiation control film

[0086] The raw material formula of the astigmatism cooling thermal radiation regulating film adopted in embodiment 1:

[0087] Recipe one:

[0088] The ratio of raw materials by weight of the astigmatism cooling thermal radiation regulation film is:

[0089] Rutile Titanium Dioxide 426 copies

[0090] LDPE 420 parts

[0091] LLDPE 83 parts

[0092] TPU 9 parts

[0093] Oleamide 13 parts

[0094] PE wax 27 parts

[0095] Far-infrared ceramic powder 20 parts

[0096] Carbon black 2 parts

[0097] Recipe 2:

[0098] The ratio of raw materials by weight of the astigmatism cooling thermal radiation regulation film is:

[0099] LDPE 32 parts

[0100] LLDPE 12 parts

[0101] 4 pieces of PVC

[0102] 43 parts of rutile titanium dioxide

[0103] PE wax 2.7 parts

[0104] Oleic acid amide 1.4 parts

[0105] Far-infrared ceramic powder 2.7 parts

[0106] Carbon black 0.2 parts

[0107] Re...

Embodiment 3

[0139] Example 3 The shading rate experiment of special astigmatism cooling thermal radiation control film

[0140] In the test field of the Academy of Agricultural Sciences, the shading rate of the astigmatism cooling thermal radiation control film, greenhouse film, greenhouse film plus sunshade net (three-needle sunshade net, shading rate of 60%) used in the present invention was tested by an illuminance meter. The experimental results are shown in Table 1 :

[0141] Table 1 Illuminance through different shading objects (unit Lx)

[0142]

[0143] Shading rate=1-sample illuminance average value / blank illuminance average value×100%

[0144] Through calculation, the shading rate of astigmatism cooling thermal radiation control film is 99.998%, the shading rate of commonly used films is 36.801%, and the shading rate of sunshade net is 79.125%.

[0145] Therefore, the astigmatism cooling thermal radiation regulating film of the present invention has a high ability to block ...

Abstract

The invention provides a method for early ending dormancy of deciduous fruit trees. The method includes a step of greenhouse temperature regulation and control. The step of greenhouse temperature regulation and control includes the following steps: keeping the illumination intensity in a greenhouse being 0-20 Lx after the greenhouse is covered with a regulation and control film; covering the greenhouse with the regulation and control film all day when the current average temperature is 10-15 DEG C; covering the greenhouse with the regulation and control film in daytime and opening the regulation and control film in nighttime when the current average temperature is 5-10 DEG C; opening the regulation and control film in daytime and covering the greenhouse with the regulation and control film in nighttime when the current average temperature is 0-5 DEG C; and covering the greenhouse with the regulation and control film all day when the current average temperature is less than 0 DEG C. According to the method, the dormancy ending time of the fruit trees is 1-2 months earlier than that of conventional protected fruit trees.

Description

technical field [0001] The invention relates to a method for relieving dormancy of fruit trees, in particular to a method for early relieving dormancy of deciduous fruit trees and a special astigmatism cooling heat radiation control film, belonging to the field of agricultural technology. Background technique [0002] At present, the protected cultivation area of ​​fruit trees in China has reached about 1.5 million mu, ranking first in the world. The protected cultivation of fruit trees aims to advance the growth and development period of fruit trees, so that the fruits can be matured and listed in early spring; The impact can achieve good economic benefits. [0003] At present, the protected cultivation of fruit trees is mainly to promote early growth. [0004] It has been found through research that the effective low temperature of 1.5-12.4 ℃ can meet the cooling capacity of fruit trees, and can release the dormancy of fruit trees as soon as possible, so that they can gr...
