How is the corn plant distance calculated? When corn is planted, it is planted by branches. There are two main types, namely, row planting and wide and narrow row planting. The distance between plant spacing refers to the distance between two corns. The row spacing refers to the distance between two rows of corn. Today, the small series says corn plant spacing. The calculation method, I hope to help everyone.
First, the calculation method of corn plant spacing
1. Single seed sowing fine seed calculation method
Precision seeding plant spacing (m) = 667 (m2) ÷ average row spacing (generally 0.57m) ÷ acres of seedlings × seed germination rate (> 92%).
1 mu = 667 square meters = 6000 square feet.
In the wide and narrow line mode, the average line spacing is calculated first.
When the seedling quality and herbicides cause a large loss of emergence, it is necessary to appropriately reduce the plant spacing and the seedlings.
2. Calculation method for semi-precision sowing seeds
Semi-precision sowing plant spacing (m) = 667 (m2) ÷ average row spacing (generally 0.57m) ÷ acres of seedlings.
When seeding with half plant spacing or one hole, the general seed germination rate is >85% <92%.
When the seedlings are fixed, the seedlings are fixed according to the plant spacing.
3. Method for calculating how many corns are in an acre of land
Number of plants = [((é•¿åœ°Ã·æ ª)+1]×[(地宽÷行è·)+1]
For example, if the land is 30m long and 20m wide, how many corns can there be if the corn is planted at a row spacing of 60cm and a plant spacing of 30cm? The substitution formula can be [(30÷0.3)+1]×[(20÷0.6)+1] = 3434 trees.
4, corn density table
a. Flat-type mid-late corn hybrids
It is advisable to keep 3000-3500 plants per acre.
b, vertical leaf type early maturity and dense maize hybrid
The seedling density per acre is 4500-5000.
c, intermediate type
The seedling density per acre is between 3,500 and 4,500 plants.
Washable Underpads are reusable pads that are designed to protect
mattresses, chairs, and other surfaces from urine, sweat, and other
bodily fluids. They are made from absorbent materials such as cotton,
polyester, or a combination of both, and have a waterproof backing to
prevent leaks.
Washable underpads come in a variety of sizes and absorbency levels, and
can be washed and dried in a standard washing machine and dryer. They
are a cost-effective and environmentally friendly alternative to
disposable underpads, and are ideal for individuals with incontinence
issues, bedridden patients, and those who are recovering from surgery or
illness.
Some washable underpads also feature antimicrobial properties to prevent
the growth of bacteria and odors, and others have non-slip backing to
keep them securely in place. They are easy to use and maintain, and can
provide peace of mind and comfort for both patients and caregivers.
