Simple Huang-Huai-Hai wheat-corn zero-crop-rotation cultivation method

Abstract

The invention relates to a simple Huang-Huai-Hai wheat-corn zero-crop-rotation cultivation method. With the goal of maximally utilizing light, temperature and water resources in a region and increasing the annual wheat-corn grain yield, a simple Huang-Huai-Hai wheat-corn zero-crop-rotation cultivation technology optimally integrates cultivation technologies for two crops, so that the purpose of annual grain production complementation, integration and balance is achieved. The technical core of the simple Huang-Huai-Hai wheat-corn zero-crop-rotation cultivation technology is as follows: after corns are harvested, minimal-tillage wheat seeding is directly carried out in conditions that soil is not turned over and straws return to the field; after wheat is harvested, minimal-tillage corn seeding is also directly carried out in conditions that soil is not turned over and straws return to the field; therefore, wheat-corn annual planting zero-crop-rotation in the Huang-Huai-Hai plain is realized; the light and temperature resources are utilized maximally; and the annual regional grain yield is increased.

Description

technical field [0001] The disclosure relates to a Huanghuaihai wheat-corn cultivation method with simplified cycle and efficient utilization of light and temperature resources. Background technique [0002] The information disclosed in this background section is only intended to increase some understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Wheat and corn are cropped twice a year as the main food production system in the Huang-Huai-Hai Plain. Before 2000, affected by the level of agricultural mechanization, this production system mainly used corn interplanting, that is, corn interplanting rows were reserved when wheat was sown. When wheat is harvested, corn is artificially sown in the reserved interplanting rows. This technology played an important role under the condition that the...

AI Technical Summary

Problems solved by technology

However, with the popularization and application of corn direct seeding technology, the problem of insufficient light and temperature resources for wheat and corn annual crops in the Huanghuaihai Plain has gradually emerged.

That is to say, if wheat is sown after corn is fully mature, wheat is likely to miss the optimum sowing time and cannot form strong seedlings before winter. On the contrary, if wheat is allowed to undergo a complete growth process, it will affect the production of corn

Against this background, some scientists use wheat and corn varieties with shorter growth periods in order to achieve annual high yields. However, the yield and quality of these varieties are worse than those of traditional planting varieties, so the actual promotion and application effect is poor

[0004] In traditional production, after corn is harvested and before wheat is sown, there are usually 8 processes of rotary tillage and straw crushing, farmland plowing, seed fertilizer spreading, rotary tillage crushing, raking, furrowing, sowing, and suppression, which consume a lot of farming time.

After the wheat is harvested, the maize stubble seeder is used to directly sow corn between the straw rows of the wheat field. Since the stubble is sown and it happens to be in the dry season, it is difficult to guarantee the emergence rate and uniformity of the corn, which limits the potential of the corn variety.
