Over the past few decades, summer maize varieties have undergone three types of “generic revolution” that have contributed significantly to advances in agricultural science and technology: rare rods, compact rods, medium-density rods。
1) rare rods: are represented by “single 13” and “farmer size 108”。
2) entrenchment of small rods: many varieties of zheng shun 958 and class 958, as well as many varieties of current zheng modified 958。
3) medium density rods: 335, as well as “category 335”, and some modified varieties。
But the wheel of history never stops。
Moreover, those who pursue scientific and technological progress have been on the road and will always be。
A new type of “revolutionary” maize species, different from the three above, has been developed — the "mixed stick" type: topaz 803, which comes from summer maize varieties that are grown in formal agricultural institutions。
The best density is 5,000 to 5,500 units per acre, and in this density zone, you can compare all other varieties, without bragging, without bullshit, with 50 kg of fertilizer per acre and with hundreds of pounds per acre per year. This is the direction of “a future agriculture” that meets the requirements of the national centre for agricultural extension。
Even if the species were reduced to the same density (4,500 units per acre) as zheng zheng zheng zheng zhou, the increase in production was marked, the increase in safety was evident — henan's seed [sweet] 202402], and the euphemism of the impostor [sweet tax204002] — the increase was in line with the standard, provided that the resistance was clearly greater than 958。
One of the greatest secrets is that the species can increase production by more than 30 per cent on a single scale (compatible with the findings of the qingdao university of agriculture) — it is not empty-planted and it has a strong edge under rare conditions。
Also, the pre-maturity of 17 leaves (three leaves less than the control variety zheng sing 958) is better suited to be insulated than that of the entire leaf, which is the advantage of the current 20- or 19- or 18-leaf variety (the reduction of leaves, the reduction of the demand for fat water alone, is more suitable for dense planting)。
In other words, the future of dense corn varieties will be the direction of validation of “minus leaves and early ripening” of 18, 17 and 16 leaves。
Let's look at the resistance of "beauje 803":
1) rodent stasis: shaanxi's identification as “combat”, henan's identification as “high resistance” and anhui as “anti”。
2) black powder: shaanxi identifies “high resistance”, henan identifies “high resistance” and anhui identifies “anti resistance”。
3) rusty disease: henan's identification of the “middle resistance” and anhui's identification of the “sense” - this is no big deal, because the breed teacher has already made improvements to the “high resistance to rust”。
4) scrutinism: shaanxi's identification as “middle resistance”, henan's identification as “combating” and anhui as “combating resistance”。
5) tattoo disease: antenna identification as “resisting”。
There is also one of the largest observations: “photo 803” is the type of angular grain of the white axis, with an oscillation, wide seed, with an seed bearing of more than 800 g/l (similar to another red axial oscillation, “twirl 1”, and high-oil protein (16% protein and fat)。
As a result of the preponderant advantages of insularity, resistance to disease, combined resistance to disease, and good seed quality, “beauyu 803” was validated in the summer of the declared country of hwang huaihai。
