Seed Counter Analysis of Effect of Boron Fertilizer on Cowpea Production
In order to ensure the high yield of crops, people often apply generously to the application of nutrient elements, ignoring the effect of micronutrients, resulting in an imbalance in the supply of nutrients to crops, resulting in poor crop growth or yield decline, and direct application of micronutrient fertilizers. The deficiency of crop micronutrients can be corrected. Boron is an essential trace element in the growth and development of crops. It plays an irreplaceable role in flowering and fertilizing the crops. Rational application of boron fertilizer is very effective in increasing crop yield and improving quality.
Test method: The area of ​​the plot was 6mzo}. The beans were broadcast live in the experimental greenhouse in April 2008, and the field management was the same as conventional production. The first spray was applied on June 13th, and then sprayed once every 10 days for a total of 3 sprays. The length of axillary length (average of 10 axillary lengths) was measured 2 days after flowering of Hung bean, and was measured every 2 days thereafter. Harvested in one month in August, and counted the seed amount (seed counter count), 1000-grain weight (seed counter count 1000 tablets, electronic weighing 1000-grain weight), and the number of pods () 60cm commodity) in each plot, and carried out the output results. analysis. Determine the germination rate and germination potential of each bean in each plot. (100 plots were selected from each plot. Seeds were germinated under appropriate conditions after germination. The seeds were inspected 1}2 times a day and water was added in time. Then the formula was measured. Seed germination rate and germination potential).
According to the participation of the seed counter, it was found that spraying different concentrations of boron fertilizer had little effect on the germination potential of Hongdou seeds, but had a certain impact on the germination rate, and the germination rates of 0.125% and 0.15% treatments were higher than those of the control. Increased by 9% and 7%. The test results show that the seed germination rate can be increased by 7% to 9% under 0.125% and 0.15% conditions.

A whole set of suspended working platform is consists of suspension mechanism , Suspended Platform, hoist, safety lock, steel Wire Rope, electric control system etc. BQ supplying all kinds of Suspended Platform Parts such as Working Platform Safety Lock, Suspended Platform Hoist Motor, Suspended Platform Brake Disc, Rectifier Module, Limit Switch and so on.
Suspension mechanism is set up at the top of the building, and hanging the suspended platform by steel wire rope. One whole set of suspended platform normally has two sets of suspension mechanism working together.
There are two safety locks for each suspended platform. They are installed separately on the safety lock bracket which is above the hoist mounting frame.
This equipment adopt anti-tilting type of safety lock. When the work platform tilts or working steel rope breaks , the safety lock can lock the steel wire rope automatically to stop the suspended platform falling down.
