Embodiment 1

[0013] Contrast experiment between potato intercropping waxy maize and single species

[0014] The potato intercropping waxy corn cultivation method adopts the following specific steps:

[0015] (1) Select land: choose soil with deep plowing layer, flat terrain, convenient irrigation and drainage, loose soil structure, good physical and chemical properties, organic matter content above 10g / kg, alkaline nitrogen content above 86mg / kg, available phosphorus content above 12mg / kg, The available potassium content is above 158mg / kg, and the soil pH is 8.0-8.2.

[0016] (2) Selection of varieties: Potatoes should be selected from early-maturing potato varieties with high yield, high quality, uniform tuber size, and good commercial properties, such as potato Lk99. For waxy corn, choose early-maturing waxy corn varieties with good waxy properties, sticky, soft and sweet taste, high yield, and strong stress resistance, such as Bainuo 6, Zhongnuo 301, and Zhongnuo 303.

[0017] (3) Din...

Embodiment 2

[0022] Example 2: Contrast experiment between topping and sowing film covering

[0023] Experimental design: strip width 1.5m, plot area 45m 2 (4.5×10), cultivate 3 ridges of potatoes and 3 ridges of corn in one plot. Potato ridges are 60cm wide, 10cm high, mulched with 800mm plastic film, and covered in two stages: topping and sowing. The potato density is 3660 plants / mu. Two rows of potatoes are planted in each ridge with a row spacing of 40cm and a plant spacing of 30cm. The corn strip width is 60cm, the plant spacing is 30cm, the row spacing is 40cm, and the density is 3660 plants / mu. Repeated three times, arranged in random blocks.

[0024] Varieties tested: Potato—the original seed of LK99, waxy corn—Bai Nuo 6

[0025] Potato fertilization: N20kg / mu, P 2 o 5 10kg / mu, K 2 O30kg / mu, three kinds of fertilizers are used as basal fertilizers, and are applied at one time.

[0026] Corn fertilization: N30kg / mu, P 2 o 5 15kg / mu, phosphate fertilizer is used as base fert...

Abstract

The invention relates to a cultivation method for intercropping intercropping potatoes and waxy corn and belongs to the technical field of crops cultivation. The cultivation method is characterized by comprising the following steps of: selecting variety: selecting the potatoes and the waxy corn from early-maturing varieties, namely the potato LK99 variety, the waxy corn Bainuo No.6, the Zhongnuo 301 and the Zhongnuo 303; laminating by means of delaying germination: carrying out laminating planting on the potatoes and the waxy corn by means of delaying germination, making ridges with the width of 60cm and the height of 10cm, spacing every two ridges at 30cm, and laminating by use of a mulching film with 800mm; and sowing: early sowing the potatoes and the waxy corn at March 8th-March 15th and at April 12th-April 18th respectively, and sowing on the film in a holing way, wherein the intercropping is carried out by the means that the potatoes and the waxy corn are respectively sown at 2 rows, the row spacing and planting distance of the potatoes and the waxy corn are same, the row spacing is 40cm, and the planting distance is 30cm. The cultivation method has the beneficial effects that the land resources and the natural resources can be abundantly used, the corps are good in ventilative and transparent conditions, and the fertilizer is high in use ratio and high in yield.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating waxy corn intercropped with potatoes. Background technique [0002] Potatoes are currently the most important food crops used as human staple food besides grains in the world. Waxy corn can be used as vegetable corn and eaten fresh by humans. The yields of potatoes and corn that require a lot of water in growth are very low in the region. For example, in Gansu Province, the general yield per mu of potatoes and waxy corn is only about 1021kg and 834kg (fresh spikes). , such as the Chinese Invention Patent Application Publication No. CN201010188934.4 discloses a corn planting method. This invention can significantly increase the corn yield, but the unit yield of the product is not high under this planting mode, and the land has been harvested in the previous year. It is idle before one year of cultivation, and the land and natural reso...
