The target yield of super rice in Heilongjiang Province is 800 kg per acre. Its theoretical structure should reach: 550 ~ 600 spikes per square meter, 85 ~ 90 spikes per ear, 25.0 g weight per spike; 450 ~ 500 spikes per acre Spike, 100 to 110 grains per spike, harvesting real grains per square meter to ensure 50,000 grains, 1000 grain weight 25.0 g. The key points of its high yield cultivation measures are as follows: 1 Selection of varieties To select medium and late-maturing rice varieties that are resistant to fertilizer, disease resistance, lodging resistance and photosynthetic efficiency. Priority identified by the Ministry of Agriculture super rice varieties: Longjing 21, Longdi 5, Songjing 9, Longjing 18.
