Embodiment 1

[0029] Potato seedling cultivation: Choose high-quality varieties with wide adaptability, drought resistance, barren resistance, fertilizer and water resistance, and storage resistance. Mix soil and miscellaneous fertilizers on the land 78000Kg hm -2 After two plows and two harrows, the ridges are 90 cm wide and 28-31 cm high. Choose potato cubes with smooth potato shape, no wounds and no pests and diseases. Soak potato pieces in a solution of 500 times 25% carbendazim wettable powder for 12 minutes before seeding. Then, from the end of March to the first ten days of April, the seeds are planted at an interval of 16 cm between each potato, and the soil is covered with 3 to 8 cm. The planting depth depends on the size of the potato. In order to prevent rodent damage and keep warm, cover the mulch film with a width of 1.0m after seeding. After the potato pieces germinate and emerge, rupture the membrane to allow the seedlings to emerge, water the seedlings to accelerate the s...

[0032] Potato seedling cultivation: Choose high-quality varieties with wide adaptability, drought resistance, barren resistance, fertilizer and water resistance, and storage resistance. Mix soil and miscellaneous fertilizers on the land 97500Kg hm -2 After two plows and two harrows, the ridges are 93 cm wide and 28-31 cm high. Choose potato cubes with smooth potato shape, no wounds and no pests and diseases. Soak potato pieces in 50% thiophanate wettable powder 400 times solution for 10 minutes before seeding. Then, from the end of March to the first ten days of April, the seeds are planted at an interval of 13 cm between each potato block, and the soil is covered with 3 to 8 cm. The planting depth depends on the size of the potato. In order to prevent rodent damage and keep warm, cover the mulch film with a width of 1.0m after seeding. After the potato pieces germinate and emerge, the membranes are broken to allow the seedlings to emerge, and the seedlings are watered to a...

[0035] Potato seedling cultivation: Choose high-quality varieties with wide adaptability, drought resistance, barren resistance, fertilizer and water resistance, and storage resistance. Mix soil and miscellaneous fertilizers on the land 87750Kg hm -2 , After two plows and two harrows, the ridges were raised, with a ridge width of 87 cm and a ridge height of 28-31 cm. Choose potato cubes with smooth potato shape, no wounds and no pests and diseases. Soak potato pieces in 600 times solution of 50% thiophanate wettable powder for 10 minutes before seeding. Then, from the end of March to the first ten days of April, the seeds are planted at an interval of 19 cm between each potato block, and the soil is covered with 3 to 8 cm. The planting depth depends on the size of the potato. In order to prevent rodent damage and keep warm, cover the mulch film with a width of 1.0m after seeding. After the potato pieces germinate and emerge, the membranes are broken to allow the seedlings t...

Abstract

Disclosed is a sweet potato and corn interplanting method. The method is implemented in late April every year and comprises the steps of (1) performing ridging after field tillage; (2) planting sweet potato plantlets at ridge tops, covering the roots of the sweet potato plantlets with soil of 5-8 cm to expose plantlet tips out of the soil for 3-5 cm, wherein the interval of the sweet potato plantlets is 18-25 cm; (3) planting corn in a mode of 2-3 seeds per hole, covering soil and enabling the interval between every two holes to be 25-30 cm. Tested by multiple experiments, the sweet potato and corn interplanting method can increase the net yield of corn by 50% under the condition of maintaining the yield of sweet potato, thereby increasing the income of grain for peasants and enhancing the economic benefits of dry lands. Further, according to the sweet potato and corn interplanting method, plantlet mulching is utilized to maintain moisture and temperature of breeding fields; restored nursery breeding is utilized to improve the emergency rate and to ensure orderly supply of the sweet potato plantlets, so that the labor intensity of the peasants can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method for interplanting sweet potato and corn. Background technique [0002] In order to implement the policy of "high yield and high income" and "multiple income and high income", it is necessary to adapt measures to local conditions and focus. In areas where there is no land available, we should reform the farming system, expand the area of ​​multiple cropping, implement intercropping, improve cultivation techniques, increase the yield per unit area, implement mixed intercropping between crops and expand the area of ​​multiple cropping to improve land utilization. An important aspect of institutional reform. [0003] Corn, also known as maize, fairy wheat, corn, corn, and cob, is an important food crop and an important source of feed. It is also the food crop with the highest total output in the world, higher than that of rice. At the same time, c...
