Problems solved by technology

Most of the two-cropping planting methods in a year are winter wheat interplanting or multi-planting summer corn, but this traditional planting method also brings many problems, mainly manifested as unfavorable for mechanized operation, heat contention between two crops, high energy consumption, soil compaction, and water resources. Serious waste, increased production costs, etc., make the agricultural production in this area unsustainable. There are many limiting factors in the production, such as unmatched good varieties and good methods, poor sowing quality, unreasonable fertilization, and serious diseases.

Embodiment 1

[0040] Annual flat cropping conventional planting mode of wheat and corn

[0041] The management of water and fertilizer and the prevention and control of diseases, insect pests and weeds adopt conventional operation methods.

[0042] Both winter wheat and summer corn were planted in flat cropping with equal row spacing, and the row spacing for wheat was 15 cm; the row spacing for corn was 50 cm, and the plant spacing was 15 cm. The wheat variety is Jimai 21, the sowing time is October 10, and the harvest time is June 4; the corn variety is Ludan 818, the sowing time is June 15, and the harvest time is September 27.

Embodiment 2

[0044] No-tillage ridge farming mode of wheat and corn

[0045] The management of water and fertilizer and the prevention and control of diseases, insect pests and weeds adopt conventional operation methods.

[0046] Use the ridge planting machine to help the ridge, the ridge width is 90cm, the ridge height is 15cm, and 3 rows of wheat are sown on the ridge. The small row spacing of wheat is 15cm, and the large row spacing is 45cm. The selected wheat variety is Jimai 21, the sowing time is October 10, and the harvest time is June 4.

[0047] After the wheat was harvested, corn was directly sown on the ridge, and two rows were planted in each ridge, with a small row spacing of 30 cm, a large row spacing of 90 cm, and a plant spacing of 15 cm. The corn variety selected is Ludan 818, the sowing time is June 15, and the harvest time is September 27.

Embodiment 3

[0049] Leisure planting mode of alternating ridge and furrow

[0050]Before sowing corn, use a ridge machine to form a ridge. The width of the ridge is 120 cm, the width of the ridge is 90 cm, the width of the ridge is 30 cm, and the height of the ridge is 15 cm. Two rows of corn are planted on the ridge. 15cm.

[0051] After harvesting corn in autumn, use a strip rotary tiller to perform rotary tillage on the wide rows, and leave high stubble (about 40cm) in the narrow rows (seedling belts) for natural rotting and return to the field. The machine sows wheat on the ridge, sows 6 rows per ridge, sows with equal row spacing, and the row spacing is 15cm.

[0052] After the wheat was harvested in the second year, a corn seeder was used to directly sow corn on the ridge, and two rows were planted in each ridge, using wide and narrow rows for planting. The wide row was 90 cm, the narrow row was 30 cm, and the plant spacing was 15 cm.

[0053] After the autumn corn is harvested, th...

Abstract

The invention belongs to the technical field of wheat and corn cultivation and particularly relates to a method for double cropping leisure plantation of wheat and corn in North China. According to a corn planting mode, the ridge width is 110-120cm, the ridge face width is 80-90cm, the furrow width is 30-40cm, the ridge height is 10-15cm, two rows of corn is planted on one ridge, wide and narrow row plantation is adopted, wide rows are 80-90cm wide, narrow rows are 30-40cm wide, and the planting distance is 10-15cm; after the corn is harvested, rotary tillage is performed on the wide rows through a strip rotary cultivator, high stubble of 35-45cm remains in the narrow rows to naturally rot and return to fields, the wide rows are ridged through a ridger, wheat is sown on the ridges through a ridge culture seeding machine, every ridge is divided into six rows for seeding, equidistant row seeding is performed, and the row space is 15-20cm; after the wheat is harvested, a corn planter is used to directly seed the corn on the ridges, and circulation is performed in a whole year. The optimized alternate leisure plantation method is adopted, reasonable water and fertilizer management, deinsectization and weeding management are adopted, all links are collaborative with each other, and the remarkable effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of wheat and corn cultivation, and in particular relates to a fallow planting method for wheat and corn twice a year in North China, and more particularly to a fallow planting method for improving the annual output of winter wheat and summer corn in double-crop areas. method. Background technique [0002] The grain production in Shandong Province is dominated by wheat and corn. Wheat and corn are harvested twice a year, which is the main grain production and planting system in the region. Their planting area and output account for more than 90% of the province's grain. The mature planting method plays an extremely important role in the agricultural production in North China. Most of the two-cropping planting methods in a year are winter wheat interplanting or multi-planting summer corn, but this traditional planting method also brings many problems, mainly manifested as unfavorable for mechanized operation,...
