High-yield simple and labor saving type maize cultivation technology

Abstract

The invention discloses a high-yield simple and labor saving type maize cultivation technology. The high-yield simple and labor saving type maize cultivation technology is characterized in that the cultivation is carried out in a wide-row narrow-width staggering dense-sowing manner; the wide row is 70cm; the narrow row is 30-40cm; the planting distance is 18-21cm; the adjacent rows are staggered; the vertical spacing of the corresponding staggered rows is the planting distance / 2; the chemical control developing assisting is carried out, namely, a developing assisting agent is applied once in the elongation stage and flare opening period; the chemical control weeding is carried out, namely, a weed killer is applied after the seed sowing and during the period that the 3 to 5 leaves grow. Compared with a traditional cultivation method, the cultivation method has the advantages that the cultivation density is large; the densifying problem can be solved by the staggering, and thus the leaf space distribution is reasonable, and the light energy utilization rate can be increased; the chemical control is carried out, so that the lodging problem can be solved, the stem internode is reduced, and the toughness is improved; the good group structure under high density condition can improve the yield increasing potential of the groups; in addition, the scientific chemical control management is carried out, and a multifunctional seeding machine (sub-soiling, seed sowing, fertilizing by layers and compacting) is provided, so that the technical purposes of simplified maize cultivation, cost saving, efficiency increasing, high yield and even super-high yield can be achieved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a high-yield, light and simple planting technology for corn. Background technique [0002] Corn is the most important food crop in my country. Under the condition of limited arable land, increasing the per unit yield of corn has become the main theme of food production, and it is also the only way to sustainably develop corn production and ensure supply capacity. Most scholars at home and abroad believe that the breakthrough of corn yield in a long period of time still depends on increasing the planting density, but with the increase of planting density, the ventilation and light transmission conditions in the group will become worse, the light energy utilization rate of the group will decrease, and the individual growth of plants will be reduced. It can be seen that unilaterally increasing the planting density has no significant effect on increasing the yield per unit area...

Problems solved by technology

But not only that, the production process of corn is a long-term process of crop growth and material accumulation. The stable development of each stage in the early stage is the prerequisite for high-yield potential in the later stage, such as plant traits (plant height, ear height, etc.), Leaf area index, dry matter accumulation characteristics, grain filling characteristics, panicle leaf net photosynthetic rate, and lodging resistance are all components that have an important impact on yield, and there is a complex relationship between these yield components and population structure. In addition, in the process of corn production, the internal morphology of the population is a gradual process. Therefore, the previous research on improving yield was too superficial and too macroscopic, and the relationship between the variable influence between the population structure and the yield components was not considered and no in-depth analysis was carried out. , failed to truly achieve the best balance between "quality" and "quantity", and there is still great potential for increasing the yield of corn

[0004] In addition, with the implementation of modern agriculture, excellent planting techniques must not only guarantee yield, but also be light and simple, so as to reduce labor burden, reduce labor costs, and facilitate popularization. Difficult, complicated management, not conducive to mechanical operation, not having the characteristics of light and simple planting, and has not been promoted in a large area
