Choosing a good mouthwash should be selected before the watermelon, tomato, cucumber, beans, garlic, leek field. It is not appropriate to plant in other vegetable fields to avoid spreading pests and diseases.
Fine soil preparation, high ridge live broadcast, reasonable and close-grained land preparation requires ground soil crushed, starting from 10 to 20 centimeters high ridges, single or double rows, conducive to drainage and irrigation. 3000-5000 plants per mu, spacing 40-50 cm, spacing 33-43 cm. Open a shallow hole and infiltrate after infiltration. Cover 0.5 cm thick soil.
Ditch matching, small water ground irrigation, timely drainage required ditch matching, irrigation and drainage convenience, small water ground irrigation, see dry see wet, to reduce the ground temperature. In high temperature weather, noon can spray water. Summer rain, prevent the accumulation of water in the field.
Reasonable top-dressing, as soon as it is promoted, management must be promoted, and no seedlings are needed. Two fast-acting fertilizers are applied in the rosette period and the filling period.
Prevent pests and virus diseases. In the early stage of disease, 20% of the virus A WP 500 times or 1.5% of the diseased lingzhi emulsion 1000 times can be sprayed and prevented. Soft rot. Chemical control. Chloramphenicol can also be used "Feng Ling" solution irrigation root. Downy mildew. Chemical control. It can be sprayed with 25% Rhodamine Mildew WP 800 times. aphid. Can be used 50% anti-inferiority WP 2000 ~ 3000 times or 40% omethoate 1000 times spray. cabbage caterpillar. 800 times BT emulsion can be used to spray, diamondback moth. Use 20% diflubenzuron 500-1000 times or 24% Wanling agent 1000 times.
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.
