Method for controlling flowering time and flowering quantity of industrial hempTechnical Field
The invention particularly relates to a method for controlling flowering time and flowering quantity of industrial hemp.
Background
The flowering amount and the flowering time of the cannabis sativa in the greenhouse industrial planting management process are related to the yield and the quality of the CBD of the cannabis sativa, most of the CBD of the cannabis sativa is contained in female flowers, the yield is higher when the cannabis sativa blooms, the harvesting times are higher, and the yield is higher, so that the cannabis sativa flowers are harvested more, and the quality of the cannabis sativa flowers and the content of the CBD are guaranteed.
Therefore, repeated experiments are carried out to solve the problem, and the method for promoting the medicinal cannabis sativa to bloom in advance and blossom more is realized by controlling the illumination time and reducing the temperature in the greenhouse by using the greenhouse heat preservation quilt.
Disclosure of Invention
The invention aims to overcome the technical defects and provide a planting method for planting medical industrial hemp by using non-woven fabric breathable and American planted bagged organic nutrient nontoxic turfy soil.
According to an aspect of the present invention, there is provided a method of controlling flowering time and amount of industrial hemp, the method comprising: big-arch shelter greenhouse, the big-arch shelter film of big-arch shelter adds the one deck heat preservation quilt outward, will the heat preservation is installed and is rolled up the convenient cover of curtain machine and take off, and whole big-arch shelter covers the lid and is tight, and wherein, control illumination time is 12 hours every day, and pure black day does not have illumination and reaches under 12 hours medicinal hemp can be under 60 centimetres left and right sides height, just can bloom in two weeks, cover 3 hours by whole big-arch shelter greenhouse with heat preservation when noon temperature is the highest, can fall to 26 degrees centigrade to the temperature of 40 degrees centigrade in the big-arch shelter greenhouse, can accord with the required temperature of hemp growth like this, can shorten the illumination time and bloom in advance.
Further, keep warm by including first layer, second floor, third layer, fourth layer and fifth layer, the first layer adopts PE snow protection frost prevention cloth to cover, and the second floor adopts thickening flower non-woven fabrics, and the third layer adopts thick sandwich cotton, and the foam insulation board after the fourth layer adopted 0.5 centimetres, and the fifth layer adopts high-quality grey non-woven fabrics, adopts the mode of making up after the five layers stack to sew up together, accomplishes the weight of 8 jin per square.
Furthermore, the heat preservation quilt is two heat preservation quilts, and the heat preservation quilts are added with adhesive tapes to be buckled together, so that the greenhouse is ensured to be light-proof and wind-proof.
The invention has the beneficial effects that: the invention can save the planting time, improve the efficiency and the yield of industrial hemp for industrial production of medicinal hemp, has low investment and obvious effect, can preserve heat to strive for the planting time for alpine regions, and shortens the cost, investment, practicability, economy and convenience.
Detailed Description
The invention is further described below with reference to specific embodiments.
In one aspect, the present invention provides a method for controlling flowering time and amount of industrial hemp, the method comprising: big-arch shelter greenhouse, the big-arch shelter film of big-arch shelter adds the one deck heat preservation quilt outward, will the heat preservation is installed and is rolled up the convenient cover of curtain machine and take off, and whole big-arch shelter covers the lid and is tight, and wherein, control illumination time is 12 hours every day, and pure black day does not have illumination and reaches under 12 hours medicinal hemp can be under 60 centimetres left and right sides height, just can bloom in two weeks, cover 3 hours by whole big-arch shelter greenhouse with heat preservation when noon temperature is the highest, can fall to 26 degrees centigrade to the temperature of 40 degrees centigrade in the big-arch shelter greenhouse, can accord with the required temperature of hemp growth like this, can shorten the illumination time and bloom in advance.
Specifically, need explain, keep warm by including first layer, second floor, third layer, fourth layer and fifth layer, the first layer adopts PE snow protection frost prevention cloth to cover, and the second floor adopts thickening flower non-woven fabrics, and the third layer adopts thick sandwich cotton, and the foam insulation board after the fourth layer adopted 0.5 centimetres, and the fifth layer adopts high-quality grey non-woven fabrics, adopts the mode of making up to sew up together after five layers of stack, accomplishes the weight of 8 jin per square.
In addition, it is worth mentioning that the heat preservation quilt is two heat preservation quilts, and the heat preservation quilts are added with adhesive tapes to be buckled together, so that the greenhouse is ensured to be light-proof and wind-proof.
The invention has the beneficial effects that: the invention can save the planting time, improve the efficiency and the yield of industrial hemp for industrial production of medicinal hemp, has low investment and obvious effect, can preserve heat to strive for the planting time for alpine regions, and shortens the cost, investment, practicability, economy and convenience.
