In the golden autumn of September, the sky is bright and crisp, and the sky is golden. In Puyang Farm Co., Ltd. of Beidahuang Group in Heilongjiang Province, a high-yield demonstration field is being harvested. Many farmers gathered on the land to watch. Several rice harvesters were "ready", and the air was filled with thick rice fragrance. This high-yield demonstration field is the plot of Jia Rujia, a planter in the eighth management area of the farm. Jia Ru said that this year he used this land to participate in the high yield creation project of the farm. The farm promoted high yield in his plot and led other growers to plant in this way. "I have 100% confidence in the technology promoted by the farm. Now it is finally time to test the harvest." The locomotive roars and moves forward slowly. The header rolls over. Pieces of rice are cut off and stored in the granary of the harvester after threshing. Jia Ru, who was driving the harvester, was full of joy. He pointed the grain outlet of the harvester at the grain truck, and golden rice grains flowed out. "This year, the harvester will run about 250 meters, and the rice harvested will fill the harvester's granary. In previous years, at least 100 meters more will be driven." Jia Ru said that this paddy field has adopted the method of sparse sowing and dense planting this year. In previous years, six or seven seedlings were planted in each hole, and this year it has increased to 10 to 12. The distance between holes is larger than that in previous years. "After rice tillering, the number of first generation ears with more grains has increased, and the number of second generation ears has increased, while the number of smaller third generation ears has decreased, so the yield will naturally rise." In the grain sunning yard of Puyang Farm Co., Ltd., the newly harvested rice of each household is stacked neatly. Jia Rujia's grain truck drives on the ground scale, unloads the grain and weighs it again. The gross weight minus the empty weight is the total weight of rice. The staff of the sun farm cracked the abacus and soon worked out the results: the gross weight of the grain truck was 10.75 tons, the net weight of the empty truck was 8.35 tons, and the weight of rice was 2.4 tons. This time, about 3.13 mu was harvested, with an average yield of 1533.55 kg per mu. Jia Ru said that the average yield per mu of his plot last year was 1360 jin. Li Hailong, general manager of the Agricultural Development Department of Puyang Farm Co., Ltd., introduced that in the past, when farmers planted rice, they used to apply foliar fertilizer only once. Now the farm encourages more accurate fertilization according to different leaf ages of rice. "As long as the rice stem is green and the temperature is appropriate, it can absorb nutrients." Li Hailong pulled up a relatively small rice spike and said that when rice grew to this stage, people used to think that fertilization would no longer be effective. Now we encourage continued spraying foliar fertilizer to promote its growth. Jia Ru calculated an account. Every time he sprayed foliar fertilizer, it cost 100 yuan per hectare. In previous years, he only sprayed it once. This year, he sprayed it six times, 500 yuan more than in previous years. This year, the farm will bear the cost. After spraying more foliar fertilizer, the rice yield per hectare will increase by nearly 2000 jin, and the income will increase by nearly 2600 yuan if calculated at 1.3 yuan per jin of rice. "Farming is no longer a matter of sowing widely and harvesting lightly." Jia Ru said that in order to have high output, it is necessary to have high input. Good technology is the guarantee of high yield and harvest. Farming should spare money. If you want to get more food, you can't count as a "small account". You must count the comprehensive account. "Last year, the average rice yield of the whole farm was 1250 jin per mu, and this year is expected to reach 1300 jin." Li Wensheng, chairman of Puyang Farm Co., Ltd., said that at present
