In winter and spring season, due to long-term feeding, lack of green feed, lack of light, easily lead to lack of vitamins in livestock and poultry, and then cause livestock and poultry metabolic disorders, growth and development stagnation, resistance to disease, and even induce disease and death. Therefore, vitamin supplements should be given to livestock and poultry in winter and spring. Now introduce a vitamin supplement that farmers can make - germination feed.
First, the production of technology Seeds of cereal crops in general, such as barley, oats, corn, rice, etc., can be used as raw materials, of which barley is the most commonly used. The method of operation is generally similar to that of raw bean sprouts. The raw material seed is screened and mixed into warm water to wash and remove sediment, pods and worms, and dry them for use. During the production, the raw materials are first soaked in warm water of 25-35°C for a day and night. After the seeds are inflated, lay them out in shallow water trays or plastic water containers of moderate size. The thickness should be 3-4 cm. Cover gauze or sacks. Then put the containers in a well-lighted and warm room to germinate. 20-25 °C is appropriate. Each day and night was sprayed with warm water at a temperature of about 30°C for 4-6 times with slight turning, and hair roots and germs were produced after 2-3 days. At this point can be removed gauze, sack film, every morning and evening, each with clean and warm water; generally after 3-5 days, shoots grow, through the green, you can feed livestock and poultry.
Second, the feeding method Under normal circumstances, such as to supplement vitamin B and improve palatability as the main purpose, buds grow out of 2-3 cm can be taken out of feeding; If the main purpose of supplementing carotene, it should be Stay until 8-10 cm long.
It has been proved that feeding female animals with germinating feed can increase normal estrus, conceive and increase lactation by feeding 150-200 grams per head per day. Feeding boars with 100-200 grams per head per day can enhance their libido. , improve semen quality, increase the rate of mating quaternia; feed young animals, 30-40 grams per head per day, piglets 10-20 grams per head per day; chicks 3-4 grams per day, can promote its growth Development, improvement of disease resistance and survival rate; supplementation of laying hens, each 10-20 grams per day, is beneficial to increase their egg production rate, fertility rate and hatching rate. When feeding, the germinating feed can be cut into small pieces or chopped into the diet as needed.
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.
