How to improve the Light transmittance of the latest greenhouse Agricultural Film
During the use of greenhouse film, due to pollution, attachment of water droplets and dust, the light transmittance will be greatly reduced, which will seriously affect the photosynthesis of crops, which is extremely disadvantageous to crop growth. Therefore, farmers need to take measures to improve the permeability of greenhouse film.

Study on the efficiency of Cotton Light Table in different planting patterns
In order to further increase the cotton yield, it is difficult to increase the number of plants per unit area. In production, it is necessary to increase the density, improve the poor ventilation and light transmittance in the middle and lower part of the cotton population, and improve the light transmittance and photosynthetic efficiency in the middle and lower part of the cotton population. In this paper, through the study of cotton population photosynthetic efficiency and light transmittance of different planting patterns, in order to determine the reasonable cotton population structure in specific areas, and to provide a basis for high-yield and high-quality cotton cultivation. Materials and methods 1. The general situation of the test was conducted in 2002-2003.

Light Control Technology of Grape cultivation in greenhouse
For grapes cultivated in greenhouse, because the light intensity in the greenhouse is often less than 70% of that outside, it has a significant adverse effect on the growth and fruit of grapes, often resulting in serious flower and fruit drop, poor fruit coloring, low sugar content, poor flower bud differentiation and so on. The yield and quality of grapes are greatly reduced. Therefore, it is enhanced.

Planting Management of Panax Notoginseng
Site selection: there are many family species of Panax notoginseng, and the cultivated land should choose Xiangyang hillside. Generally speaking, sandy black loam is the best soil, ash soil is the second, red soil is the second. Clay is not suitable for cultivation. Site selection is one of the important factors for the success or failure of the introduction of Panax notoginseng. It is appropriate to choose a hillside with an elevation of 700 mi 1500 meters, Dongyang and a slope of 10 mi 20 degrees. In the low mountain area or hilly plain area above 400 meters above sea level, the diseases and insect pests are more serious, and the leaves often fall off in the early stage. Experience has proved that it is better to choose a cool and ventilated hillside with high mountain shade in the west.

Key points of management of plastic film garlic returning to green
1. The key to purify the surface of plastic film and increase the light transmittance of garlic is the temperature, and the main management in this period is to improve the ground temperature. For garlic covered with plastic film, the mulch on the film, such as leaves, completely dead garlic leaves and dust, should be removed as soon as possible to purify the film surface in order to increase the transmittance and raise the ground temperature. The damaged plastic film should be repaired in time to increase the heat preservation and warming effect and promote the garlic to turn green as soon as possible. two。 The root system of garlic is not resistant to moisture, and it is easy to cause rotten roots when it comes to spring rain and stagnant water in the field.

Planting technology of Panax notoginseng
It is better to plant Panax notoginseng in sandy black loam, cover it with mixed fertilizer soil after sowing, and then cover it with a layer of turf. A year later, it was planted in another place. Adjust the transmittance of the ceiling properly. Get rid of weeds in the field in time, and fertilize four to eight a year.
