Nutrition knowledge ã€Introduction to Magnolia Knowledge】: Magnolia is a dry bud of Magnoliaceae plants such as Magnolia, Magnolia and Wudang Magnolia. Magnolia is a deciduous tree, born in a hillside forest 400 to 2,400 meters above sea level. It is located in the south part of Henan, Shaanxi, Gansu, western Hubei and Sichuan, Anhui, Zhejiang, Jiangxi, Hunan, and Guangdong. When spring buds are not yet open, Qi Peel at the peduncle, under the sun exposure during the day, piled up in the evening, sweating, so that the inside and outside the wet and dry uniform, dry to 50% dry, stacking 1 to 2 days, then dry to dry, in case of rain, can be dried. The dry buds of Magnolia spectabilis are brush-shaped or long-oval, 1.2 to 2.5 cm long and 1 to 1.5 cm in diameter. Sepals 2 to 3, 2 per layer, densely gray or grayish green hairs on outer surfaces, glabrous and tan on inner surface. Tepals 9, 3, tan. In addition to the quilt, there are numerous brown stamens and pistil. The body is light and brittle, gassy, ​​spicy and slightly bitter. Magnolia dry buds are 1.5 to 3 cm in length and 1 to 1.5 cm in diameter. The outer surface of the sepal was covered with greyish white or grayish green hairs, and the tepals 9 had no significant difference between the inner and outer wheels. Wudang magnolia buds are 3 to 4 cm long and 1 to 2 cm in diameter. The outer surface of sepals is densely yellowish or yellowish green, while some sepals are dark brown in appearance. Tepals 10 to 15. There is no significant difference between the internal and external wheels. All buds are large, not open, yellow-green color, no branches are better. [Xinyi supplement information]: According to the different processing methods, is divided into Magnolia, fried Magnolia, honey Magnolia, after processing, storage and drying containers, fried Magnolia, honey Mimian airtight, home cool and dry place. ã€Xingyi suits the crowd】: Yin Huowang is careful. ã€Magnolia Diet Therapy】: Xinyi Spicy, Sexual Warmness; Lung, Stomach Meridian; Fragrance With chills and dispels cold, stop pain Indications of cold headache, dizziness, snout, nasal cold runny nose, toothache, facial swelling. [Mingyi food phase g]: Magnolia and five stone fat phase g; not with calamus, Puhuang, Coptis, gypsum with the use. [Xinyi practice guidance]: 1. Where the disease is cold, nasal clearing, sneezing more than those, can be equivalent to wind, white peony, Asarum, Chuanxiong. 2. If the nose is turbid, the yellow thick is hot and smelly and the symptoms are wind and heat. It can be used with mint, astragalus and honeysuckle. 3. If the duration of the disease is long, the gall bladder is guilty of the disease, and if you see any turbid sensation, such as pus, unpleasant odor, and smelly smell, you can treat it with Bupleurum chinense, Fritillaria and Fritillaria. 4. The product can also be used for external purposes, such as the goose does not eat grass fried nose and drip, or with fish brain stone into the nose and nose treatment, or with hops, etc. for the treatment of toothache and so on. Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.

The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
