Embodiment 1

[0020] A high-yield cultivation method for interplanting sweet potatoes with corn, comprising the following steps:

[0021] (1) Land plot arrangement: Select land with good soil conditions, loose soil quality, convenient drainage and irrigation, and good air permeability as the interplanting plot. In late March each year, the ridge height, The ridges with ridge distances of 25cm and 75cm are prepared;

[0022] (2) Seed selection and planting: choose varieties with early maturation period for corn, and choose yellow heart potato for seedling cultivation for sweet potatoes. When the height of potato seedlings reaches 20cm and the surface soil temperature is 17°C, the seedlings are cut horizontally and shallowly inserted. When the surface soil temperature is 10°C, Interplant 1 row of corn with sweet potatoes every two ridges, sow 2 grains in each hole, and the plant spacing is 33cm;

[0023] (3) Field management: After the sweet potato is planted alive, loosen the soil, weed and...

Embodiment 2

[0027] A high-yield cultivation method for interplanting sweet potatoes with corn, comprising the following steps:

[0028] (1) Plot arrangement: Select land with good soil conditions, loose soil, convenient drainage and irrigation, and good air permeability as the interplanting plot. In the first ten days of April each year, the ridge height, The ridges with a ridge distance of 26cm and 78cm are prepared;

[0029] (2) Seed selection and planting: choose varieties with early or mid-early maturity for corn, and yellow heart potato for sweet potatoes to grow seedlings. When the height of potato seedlings reaches 22cm and the surface soil temperature is 18°C, the seedlings are cut horizontally and shallowly inserted, and the surface soil temperature is 18°C. At ℃, one row of corn was interplanted with sweet potatoes every two ridges, 3 seeds were sown in each hole, and the plant spacing was 34 cm;

[0030] (3) Field management: After the sweet potato is planted alive, loosen the...

Embodiment 3

[0034] A high-yield cultivation method for interplanting sweet potatoes with corn, comprising the following steps:

[0035] (1) Land plot arrangement: Select land with good soil conditions, loose soil quality, convenient drainage and irrigation, and good air permeability as the interplanting plot. In late March each year, the ridge height, The ridges with ridge spacing of 27cm and 80cm are prepared;

[0036] (2) Seed selection and planting: choose varieties with early or mid-early maturity for corn, and yellow heart potato for sweet potato seedlings. When the potato seedling height reaches 23cm and the surface soil temperature is 19°C, the seedlings are cut horizontally and shallowly inserted. When the surface soil temperature is 13 At ℃, every two ridges of sweet potatoes are interplanted with 1 row of corn, 4 seeds are sown in each hole, the plant spacing is 35cm, and the planting densities of sweet potatoes and corn per hectare are 50,000 plants and 30,000 plants respective...

Abstract

The invention provides a high-yield cultivation method of corn-sweet potato interplanting. The high-yield cultivation method comprises the following steps: (1) readjustment of a field plot: selecting land with good soil conditions, loose soil, convenient irrigation and drainage and better air permeability as an interplanting plot, (2) seed selection and planting: selecting a corn variety with an early or immediate early mature period and selecting yellow pulp sweet potatoes for seedling raising, (3) field management, (4) insect and disease prevention, and (5) timely harvesting: harvesting the corn when more than 80% of subtending leaves are withered, cutting off straws to carry away unifiedly, and harvesting the sweet potatoes when the average daily temperature drops to 15 DEG C. The interplanting method is a scientific and reasonable cultivation method from the field plot readjustment, the seed selection and growing, the field management, and the insect and disease prevention to the timely harvesting; the corn has strong wind resistance and good quality; several tests demonstrate that the yield of the corn is increased by 70% under the condition that the yield of the sweet potatoes is not changed; the economic benefits are effectively improved; the interplanting cultivation method is simple, easy to operate and popularize.

Description

technical field [0001] The invention relates to the technical field of agricultural product cultivation, in particular to a high-yield cultivation method for interplanting sweet potatoes with 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 r...
