Experts advise: late mature corn can not be planted

“If the late-maturing corn varieties suitable for low-latitude planting are planted at high latitudes, if they cannot be normally matured before frost, different levels of 'water corn' will appear.” According to the person in charge of the Heilongjiang Provincial Seed Administration, this may lead to food The quality has declined and farmers have not increased their output.

According to agricultural experts, each species has its own adaptation area. Only when it is cultivated in a suitable area can it achieve stable production and high yield. Since the beginning of the winter, precipitation in Heilongjiang province is relatively low, soil moisture is poor, and there may be periodic early frost, and late planting of late-maturing varieties may significantly reduce yield.

It is understood that Heilongjiang Province has issued a regional layout plan for high-yield and high-quality varieties of major grain crops in 2012. In the province's first to sixth accumulated temperature zones, several high-yield and high-quality varieties of major grain crops were recommended. Experts suggest that farmers should fully understand the characteristics of crop varieties, cultivation points, scientific selection of fine varieties, and prevent crop varieties from being planted.
