(2) The row spacing, the amount of broadcast, and the row spacing of the marker are determined according to the technical requirements for agricultural production. The number n of openers that can be installed can be calculated as follows:
n=L valid/b +1
L effective: opener mounting effective beam length b: line spacing If the calculated opener is singular, the middle opener is installed in the middle of the opener mounting frame; if it is even number, install it. The center of the rack is symmetrically mounted on both sides symmetrically.
When the transmission speed ratio is fixed, the seeding amount can be changed by changing the working length of the seeding sheave with the sowing amount adjustment handle. The greater the length of the groove wheel into the seed box, the larger the broadcast volume; otherwise, it is small. According to the requirements of agriculture and production, the actual seeding rate q can be calculated as follows:
q=Mill sowing volume (kg/acre) π seeder ground wheel diameter (m) Number of rotations of the ground wheel Line spacing (m) (1+ground wheel slip coefficient)/666.7 (kg)
The specific method is to support the seeder so that the seed box is horizontal, the ground wheel can rotate freely, the opener is dropped, and the seed amount adjustment handle is placed in a suitable position. Add - a fixed number of seeds, and include seedlings, and inoculate the inoculation bag under the seedlings. Then, at a speed similar to that of the formal work in the field, 2030 turns of the walking wheel is evenly turned and the amount of seeds in each inoculated bag is weighed. After recording, the actual calculated seeding amount q is compared (the actual calculated ground-slide coefficient - Take 0. 050. 1).
Marker length calculation. In order to make the row spacing of the adjoining two row spacings normal, no replays and missed broadcasts will occur, guiding the tractor to run correctly, and the length L of the marker (distance from the furthest row opener to the marking line). Tractor center line alignment trace: L=(B+b)/2
If the tractor is eccentrically driven, the right front wheel of the tractor is often used to align the prints so that the left and right print lengths are different:
L left (B+b)/2+A/2
L right (B+b)/2-A/2
B: broadcast amplitude b: line spacing A: center distance of the front wheel of the tractor (3) Before pilot planter operation, field trial broadcasting should be conducted first, and the amount of sowing, broadcast depth (achieved by adjusting the depth of opener ditching), and cover soil Check the quality, adjoining row spacing, etc., until all items are in compliance with the requirements. First calculate the number of return seeding Q (kg):
Q = 2 acres sowing volume (kg) broadcast amplitude (meters) sowing length (meters) / 666. 7
Then add - quantitative seeds in the seed box and scrape them, make a mark, add a round trip of the sowing seeds to the seed box and sowing. After the broadcast-a round trip, see if it is flush with the mark; if not, adjust the position of the adjusting handle, and then perform the trial broadcast until it meets the requirements.
(4) Checking the seeding quality Often, check the various seed metering devices using the groove working length template to see if there is any change. Randomly take more than 10 measuring points along the diagonal direction of the plot to check the sowing depth. The deviation should not exceed plus or minus 1 cm. Check the number of seeds actually planted per m length in the broadcast. m,m can be calculated as follows:
m = Mu sowing volume (kg/mu) Row spacing (m) 106/666. 7 thousand grains (g)
After the completion of the plot and the area of ​​the plot, check the area sown, the actual seeding rate and the mu planting rate, and adjust if the requirements are not met.

If you get slow effects from using Human Growth Hormone or Bodybuilding Peptides alone and want a faster effects,you can try to use anabolic steoids.You must have a question [How can I get the anabolic steoids oils with real dosage and high purity?"Homebrewing steroids oils by your own through buying raws steroids will be the most reliable way to guarantee you get the real dosage and clean stuff.But some people will say [I`m busy and have no time to do it by myself",no worries,buying Semi-Finished Steroids Oils from reliable raws steroids and Sarms Raws source is the best choice if you have no time to homebrew steroids.You just need to filter Semi-finished Steroids Oils,then you can get high purity steroids to use.
First, we have to make it clear that the semi- Finished Steroids oils which we are offering are actually "finished". It means that the oils are produced with our high purity steroid raw powders, BA, BB and carrier oil (GSO, CSO and EO, etc.) already.

How to Filter semi-finished steroids oils?
Filtering is just a simple process to let the semi-finished steroids oils get through the filter membrane.
During this process, since the size of most of the bacteria are larger than 0.6 um, so the pore size of filter membrane 0.22 or 0.45 um will be good, the bacteria will leave behind on the filter membrane and thesemi-finished steroids oilsbecome sterile and safe for injection.
To filter semi-finished steroids oils, according to the quantities, there are mainly 3 types of filters, vacuum pump filter set, bottle top filter set and syringe filters. And the most recommended is bottle top filter set. For most of customers who are producing bulk batches of final products of steroid injectable, vacuum pump filter set,
How to Get the Filtered Oils Into Sterile Vials?
For those who want to start their own business by producing steroids by themselves, this might help.
To produce finished steroid products, the device for getting those filtered oils into vials will be required. There is a very popular device - the dispenser. It will help to get your liters of oil conversions into 10 ml vials. Dispenser will be operated manually.
On the other hand, the peristaltic pump will also work, but it's automatically, your life will be easier with peristaltic pump.
How to Make Stoppers and Vials Sterile?
Sterilization of vials and stoppers:
#1. Clean your vials:
a. Wash with soap and distilled water, rinsing with distilled water;
b. Rinse a second time with an alcohol of your choosing. Isopropyl is also a good choice. Acetone is also acceptable.
#2. Dry and Heat your vials:
a. Place them upside down on a baking sheet that has been properly wiped with an antiseptic;
b. Preheat oven to 350*. Place vials in oven and let set for about 30 mins, allow the vials to cool to room temp and then repeat the process.
#3. Soak stoppers in a hydrogen peroxide solution for a minimum of 10 mins.
