What kind of cotton seeds are considered good cotton seeds? There is no definite standard for the quality of cotton varieties. What principles should be followed when selecting cotton seeds? The following six points for reference.
First, we must choose the varieties approved by the Crop Variety Approval Committee above the provincial level.
Second, we must look at the number of certified varieties and the defined scope of cultivation.
Third, it depends on whether the variety has production licenses, business licenses, and quarantine certificates.
Fourth, we must understand that the purity of conventional insect-resistant cotton seeds should reach more than 98%, and the purity of hybrid insect-resistant cotton F1 should be more than 95%. Hybrid F1 should be used as far as possible, and hybrid F2 should not be used.
Fifthly, farmers with large area of ​​cotton planting should be guided to use one or two local main push varieties.
Sixth, it is necessary to use certain bivalent (including two insect-resistant genes) transgenic insect-resistant cotton varieties because the resistance to insects of bivalent transgenic insect-resistant cotton is more stable and lasting.
In the United States and Canada, an Electric Blanket is a blanket with an integrated electrical heating device usually placed above the top bed sheet. In the United Kingdom and Commonwealth, electric blanket commonly refers to an electric underblanket (electric mattress pad), which is placed below the bottom bed sheet. Electric blankets usually have a control unit which adjusts the amount of heat the blanket produces. Blankets for larger sized beds often have separate controls for each side of the bed. The electric blanket may be used to pre-heat the bed before use or to keep the occupant warm while in bed.
Some modern "low voltage" electric blankets (such as Car Blanket) have thin carbon fiber wires and work on 12 to 24 volts. These blankets are more comfortable and even safer than ordinary 110/240 volt blankets.
