Second, the operating procedures 1, select the appropriate combination of varieties. According to the local variety resources, consider the background diversity of the genetic varieties, disease resistance, agronomic traits and economic traits. Generally, the local high-yield, short-bar, and more resistant varieties are selected as the main planting varieties, and the high-quality rice, fragrant rice, and glutinous rice are used as the intercropping varieties of the high-bar, and the main dwarf varieties and the supporting interplanting varieties are required. The difference is more than 30 cm, and the growth period is basically the same. Generally, the difference cannot be 7 days. The combination of varieties should be selected according to the opinions of the local county plant protection station, or consult the provincial plant protection station.
2. Cultivation requirements. According to the production requirements, each mu is planted at a scale of 20,000 bushes/mu. The way to plant is as follows:
×○○○○○×○○○○○×○○○○○×○○○○○×○○○○○×
×○○○○○×○○○○○×○○○○○×○○○○○×○○○○○×
×○○○○○×○○○○○×○○○○○×○○○○○×○○○○○×
×○○○○○×○○○○○×○○○○○×○○○○○×○○○○○×
Note: ○ is the main plant variety, generally a short pole, × is a planting variety, generally a high pole, the height difference between the high pole and the short pole is 30 cm; the main planting variety can be transplanted, or thrown, The planting variety can't exceed two lines, so it is better to act.
3. Pest control. Rice seeds are soaked with 25% ampoules 2000-3000 times before sowing for 24 to 48 hours, then germinated or sowed; 3-5 days before transplanting, a “give medicine†is applied, and the pesticide varieties can be based on local rice diseases. Insect control object selection; in the year of common rice blast disease, leaf mites are not applied for prevention and treatment. In the 3 days before heading, 3 (3 - 3 g of tricyclazole) or 100 ml of Fuji 1 is used, and 30 kg of water is sprayed to prevent the neck. plague.
Third, matters needing attention 1, the selection of varieties should be selected according to the opinions of the local plant protection station, the height difference between the varieties should be more than 30 cm.
2, the application of this technology is not guaranteed not to cause rice blast, but to greatly reduce the incidence and reduce the damage caused by rice blast.
3. The variety growth period is inconsistent, and the sowing date can be adjusted to ensure that the maturity of the selected varieties is basically the same.
4, interplanting varieties can not be inserted more than two lines, otherwise it will affect the effect of controlling rice blast.
5. Other pest control should be carried out according to the instructions of the local plant protection station.
The product uses own mold to make technologic design, the housing uses aluminum and silicon alloy and upper protrusion and lower sinking structure is used so as to ensure good sealing performance; protective grade reaches IP 68.
Main parts are imported, wiring bar is welded with precise anti-surge electronic components, which can prevent Load Cell damage caused by lightning and power grid surge voltage.
Whole device uses stainless steel grounding bolts to ensure reliable grounding during operation.
Assembly of junction box uses not-loose screws so as to avoid loss during load cell wring.
Wiring board uses combined screws for assembly, which are convenient for removal.
In order to ensure protective effect, force and diameter of tightening parts have introduction.
I. Technical Introduction Rice blast is a fulminant rice disease that can have a devastating effect on rice yield. It is difficult to control, costly and has poor results. The Provincial Plant Protection Station introduced the rice blast disease technology using the diversity of rice varieties studied by Yunnan Agricultural University. After two years of experimentation and demonstration, it has achieved good results. In the application area of ​​rice blast, it can increase the income and expenditure by 10-15%. The technology is simple and easy, and can reduce the dosage of medicines 1-2 times, which is in line with the requirements for producing green rice.
