Is it better to wait for the line or the size of the corn planting method? (calculation method is included)

Corn (most crops) is planted in branches, divided into equal rows and wide and narrow rows. The plant spacing of corn (called ridge spacing by some farmers) refers to the distance between two adjacent plants in each row of corn; the row spacing of corn refers to the distance between two adjacent rows of corn.

The calculation method of plant distance of corn:

1. Sowing high-quality seeds with a single seed

Precision sowing plant spacing (m) = 667 (m2) / average row spacing (m, generally 0.57 m) / number of seedlings per mu × seed germination rate (generally greater than 92%); 1 m = 3 ft = 30 inch. It is the same by ruler, 1 mu = 667 square meters = 6000 square feet.

The wide and narrow row mode can first calculate the average row spacing. When the seedling emergence loss caused by sowing quality and herbicides is large, the plant spacing should be reduced properly. For example, seeds such as Mei Yu 5 and Yuhe 988 of Yuyu seed industry are seeds that can be sown individually. The seed germination rate marked in the product package is greater than or equal to 92%. The germination rate test results are all between 95% and 99%, and some are as high as 100%.

Warm reminder: excellent sowing requires very high seed quality (especially germination rate and cleanliness), and the incidence rate is less than 92%. You can't sow a single seed with precision.

2. Semi-precision sowing seeds

Semi-precision sowing plant spacing (m) = 667 (m2) / average row spacing (m, generally 0.57 m) / number of seedlings per mu; 1 m = 3 ft = 30 inch. When using half-plant distance or two seeds in one hole, the general seed germination rate is more than 85% but less than 92%. When the seedlings are fixed, the seedlings are fixed according to the distance between the plants, and when the seedlings are missing, there are two plants in the nearest hole.

3. How to calculate the number of corn plants in a piece of land?

Number of plants = [(ground length / plant spacing) + 1] × [(ground width / row spacing) + 1]

For example, for a plot of land 30 meters long and 20 meters wide, how many corn trees are planted according to equal row spacing of 60 cm and plant spacing of 30 cm?

[(30 / 0.3) + 1] × [(20 / 0.6) + 1] = 3434

4. Corn density table

The planting density of maize is one of the factors directly affecting the yield of maize. According to local conditions, select varieties suitable for local planting, and choose reasonable density according to variety characteristics, yield level, soil fertility and fertilization level, in order to greatly improve maize yield.
