Agricultureis a countryEconomyAn important pillar of life, and food as a basic need of human life, forAgricultural developmentIt is of great significance. Over the past few years,Summer cornThe production of the production has gradually increased, but there is still a lot of room for improvement. In order to pushSummer cornThe yield is further increased and decreasedFarmersThe cost of fertilization, watering and spraying was initiated by the Science and Technology Advisory Group of the Northern Rural NetworkSummer corn"Tons of grain abundance project". The project unites more than 10 companiesSeed industryThe company and scientific research units aim to promote through scientific and technological innovation and demonstrationFarmersBring tangibleEconomyBenefits and benefits. After years of hard work, 2024Summer cornThe "ton grain abundance project" has been fully opened, and the goal of 3,400 catties per mu in two seasons is about to be achieved.
In order to improveSummer cornWe optimized the yield per mu from two aspects: variety selection and sowing density. Based on past practical experience, we chose three ones with different densitiesSummer cornvarieties are compared.
1. Density of 3500 plants: "Shixing No. 3" or "1020" varieties are mainly selected, and the fertilization per mu does not exceed 40 kg. These varieties are suitable for planting at a density of 3,500 plants, and can be increased by limiting the amount of fertilizer.
2. Density of 4000 plants: choose "Horizontal Width No. 1" or "Hongyu No. 1" productPlanting-based, fertilization per mu does not exceed 40 kg. These varieties are suitable for planting at a density of 4000 plants, and the yield can be increased by increasing the planting density appropriately.
3. Density of 4500 plants: select".Hanyu Jinhuan No. 9".or"Yuanfeng 978" varietyMainly, no more than 40 kg of fertilizer per mu. These varieties are suitable for planting at a density of 4,500 plants, which can be increased by intensive planting.
Through comparative experiments and field demonstrations, we found different varieties and densitiesSummer cornAll of them can achieve a significant increase in yield under the premise of no more than 40 kg of fertilizer per mu. This not only saves costs, but also improves land efficiency, for:Farmersbrought a considerable oneEconomyEarnings.
Why we willSummer cornThe amount of fertilizer is limited to 40 kg per mu? This is a question worth parsing.
Summer cornBorrow the previous stubbleWheatFertilization:Summer cornWinter before plantingWheatCrops can provide enough nutrients to makeSummer cornAble to grow well with limited amount of fertilizer. In this way, it not only realizes "one fertilizer for two purposes", but also can effectively save the cost of fertilization.

Therefore, we have decided to completely eliminate those "dwarf stalks and large spikes", poor disease resistance and disease prone from 2024Summer cornVariety. We want to choose varieties with the following bottom line requirements:
1. Must be drought-resistant: the temperature is high in summer, the rainfall is unstable, and the drought resistance isSummer cornAn important indicator of the variety.
2. Must be able to "live straw maturity": live straw mature varieties can increase yield by at least about 20%. Such varieties usually have a well-developed root system that is both able to satisfyCornThe requirement of "less fertilizer and higher yield" can also promote stubbleWheatStable and high yield.
3. The yield of a single spike must be increased by more than 30%: in the case of sparse planting or lack of seedlings, the variety can have a good compensation effect and improve the yield.
4. It must be a cylindrical spike, and the bracts have no wilt spots or mildew: such a spike shape is conducive to sunlight and nutrient absorption, and improves yield.
5. Must be highly resistant to stem rot and rust: on the basis of ensuring high resistance to rust, it must also be able to resist stem rot and other diseases. Only such varieties can meet our requirements.
On the premise of the above bottom line requirements, we can continue to seek other varieties with more advantages to further improveSummer cornyield and quality.
PassedSummer cornWe have seen the implementation of the "Ton Grain Abundance Project".Summer cornHope for increased yields. We achieved this by optimizing variety selection and sowing density, and by limiting the amount of fertilizer to be appliedSummer cornThe target of 3,400 catties per mu. At the same time, we also improve by eliminating unqualified varieties and selecting varieties with disease resistance and yield advantagesSummer cornquality.

However,Summer cornThere are still some challenges to increasing production. In future work, we need to further research and promotionSummer cornplanting technology, cultivating more scientific and technological talents, improvingFarmersThe quality of science and technology.
