Sow a good seed in a seed.
Precision sowing spacing (m)=667(M2)÷ average row spacing (m, generally 0.57 m)÷ number of seedlings per mu × seed germination rate (generally above 92%); 1 m =3 feet =30 inches.
According to the ruler, 1 mu =667 square meters =6000 square feet.
In wide and narrow line mode, the average line spacing should be calculated first. When the sowing quality and herbicide cause great loss of seedlings, the spacing between plants should be appropriately reduced without thinning seedlings.
Tips: Precision sowing requires high seed quality (especially germination rate and purity). When the germination rate is lower than 92%, single seed precision sowing is not allowed.
Semi-precision sowing
Semi-precision sowing spacing (m)=667(M2)÷ average row spacing (m, generally 0.57 m)÷ number of seedlings per mu; 1 m =3 feet =30 inches.
When two kinds of seeds are used, the germination rate is generally above 85%, but below 92%. Seedlings should be fixed according to the distance between plants. When the seedlings are short, leave two plants nearby.
Row spacing of fruit and corn planting
Row spacing is generally between 50 and 60 cm, 33 to 40 cm in spring and 25 to 33 to 40 cm in summer. In this way, the density of spring sowing corn can reach 3300-4000 plants/mu, and summer sowing corn can reach 4000-4500 plants/mu.
At the same time, the row spacing should be determined according to the characteristics of varieties. Varieties with small angle between stems and leaves, flush leaves and developed roots should have narrow row spacing; For large spike varieties, the stems are tall, the leaves are flat and the row spacing can be wider.
The above is the introduction of plant spacing and row spacing of fruit corn planting. In order to improve the planting efficiency of fruit corn, the plant spacing and row spacing of fruit corn have certain standards. Growers should choose reasonable density according to the characteristics, yield level, soil fertility and fertilization level of fruit corn in order to obtain high yield.
