JPS63296634A - Method for selecting plant utilizing vinylhouse - Google Patents

Abstract

PURPOSE:To enhance selection effects and breed plants, by cultivating crops in a vinylhouse overlappingly spread with plural vinyl sheets with an interval therebetween, making environment, such as temperature, wind and rain, uniform, reducing the amount of solar radiation and spindly growing plant bodies. CONSTITUTION:Crops are cultivated in a vinylhouse prepared by overlappingly spreading double - triple vinyl sheets with a thin interval between the respective vinyl sheets so as to provide uniform environment, such as temperature, wind and rain, reduce the amount of solar radiation and increase scattered light. Thereby plant bodies spindly grow due to the reduced amount of solar radiation and the amount of assimilation is increased by an increase of scattered light. Tissues and organs of the plants are grown into a characteristic form and selection effects can be enhanced to breed the plants. Furthermore, more accurate effects are obtained by forming the vinylhouse in a glasshouse or air conditioning room for enhancing regulating effects in temperature and humidity and preventing dust from the surroundings.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention maintains mild and stable weather conditions in a vinyl greenhouse with little influence from wind and rain, reducing the amount of sunlight and increasing scattered light. Emphasize and utilize the artificial weather environment, cultivate plants in this environment, and fully express their characteristics.

Food breeding focuses on the wide variety, diversity, and polymorphism of traits that occur during the process of plant growth, making use of trait changes, and setting indicator formats to increase the effects of selective selection. It is about law.

(Conventional technology) Vinyl greenhouses are originally advantageous for intensive cultivation and can easily provide a uniform and mild artificial climate environment, so they can be used for forced cultivation, kept warm for winter cultivation, and used for seedling raising. or widely used.

On the other hand, they also have disadvantages, such as their ability to retain heat is weaker than a glass room, the amount of sunlight is reduced, plants grow too long and become weak, and plant diseases are more likely to occur.

(Problems to be Solved by the Invention) The present invention makes full use of the agricultural environment of a vinyl greenhouse, which is a simple, mild, and uniformly populated environment suitable for intensive cultivation, and also allows light to pass through the vinyl. However, the amount of scattered light and conspicuous light increases, and overall sunlight decreases.
This is an attempt to perform solid selection of plants by taking advantage of the tendency of plants to become elongated.

In other words, when cultivated uniformly, selection is possible based on the differences in characteristics between individuals, and if the plants grow elongated due to a decrease in the amount of sunlight, individual differences become larger and more clearly expressed, and the selection effect becomes less effective. The aim is to utilize this increasing phenomenon for plant breeding.

(Means to solve the problem) It is the same as the scope of claims and will be omitted.

(Function of the invention) Since the vinyl house according to the present invention has a large number of vinyl sheets, the heat retention effect inside the greenhouse is large, and it is warm in winter and suitable for cultivation, but in summer, the temperature becomes too high and the growth of plants is hindered. It becomes impossible.

In such cases, it would be best to round up the area where the plastic touches the land to let in the wind, or dig up the soil to let the wind circulate.

Furthermore, by installing an air conditioner in a glass room and creating a plastic greenhouse with overlapping layers inside, it is possible to set even more accurate environmental conditions.

(Effects of the Invention) In the present invention, the environment such as temperature and humidity inside the greenhouse tends to be uniform and mild, and cultivation is carried out uniformly and intensively by watering, fertilizing, weeding, etc.

In a vinyl greenhouse, sunlight passes through the vinyl, reducing the amount of sunlight, causing plants to grow larger and their tissues to grow softer.

This is a drawback as it makes virus diseases more likely to occur, but in this project, various characteristics and traits are expanded and expressed as the plant grows and grows. This produces an effect that promotes selection and culling effectively, and this can be used for individual selection and plant breeding■

Claims (1)

[Claims] In order to enhance the selection effect by cultivating in a uniform environment with reduced amount of sunlight, the following method was used. By equalizing the environment such as temperature, wind and rain, and reducing the amount of sunlight,
To increase scattered light, build a vinyl house with two or three layers of vinyl. In order to increase the effect of regulating temperature and humidity and prevent contamination due to dust from the outside, it is possible to create a vinyl house in a glass room or artificial climate room to reduce the amount of sunlight and increase scattered light. More accurate. It will be more effective if you leave a thin gap between each vinyl. When plants are cultivated under such overlapping vinyl greenhouse environment with uniform environmental conditions and reduced amount of sunlight, the plants grow elongated. A large number of solid plants are cultivated under uniform environmental conditions in terms of temperature, humidity, sunlight, etc., and the characteristics of the plants are improved through highly intensive cultivation, including providing sufficient moisture through watering, fertilizing, weeding, etc. to fully express and develop. During the breeding process, animals are selected according to certain criteria according to the selection goal, and individuals with good characteristics are retained. As mentioned above, in order to take advantage of the properties of vinyl that moderately reduces the amount of sunlight and scatters strong solar radiation, and to make effective use of this effect industrially, two to three
Crops are cultivated in heavily overlapping greenhouses, elongating due to the decrease in the amount of sunlight, and increasing the amount of assimilation due to scattered light, resulting in the formation of plant tissues and organs into a distinctive form. A plant breeding method that is characterized by increasing the selection effect for important traits that cannot be selected through normal cultivation.
