Embodiment 1

[0031] In this example, 5 different treatments were set up to explore the influence of different intercropping densities on economic benefits per unit area. The test base was selected at Baodongyu Base, Guanjiaping Community, Zhangjiang Town, Taoyuan County, Hunan Province. The experiment used Xiangcaishu No. 2 and Meikui Zaoli 667 as test materials. A total of 5 treatments were set up, including 3 treatments with different sunflower intercropping densities and 2 crops as single crop controls. The rest of the steps were the same. The specific density settings are shown in Table 1. The area of ​​the plot is 0.1 mu, repeated 3 times, arranged in random blocks. Vegetable sweet potatoes were planted on April 13, and agronomic measures such as normal water and fertilizer management and seeding were carried out during the growth period. The oil sunflower was planted on April 21 after the vegetable sweet potato survived, and was harvested on July 21. After the harvest, 2 rows of veg...

Abstract

The invention relates to the technical field of crop cultivation methods, and particularly discloses a cultivation method used for interplanting vegetable sweet potatoes and oil sunflowers. The methodcomprises the following steps: A, selecting varieties; B, raising seedlings; C, performing planting and performing sowing; D, performing field management; E, harvesting stems and leaves; and F, planting autumn sweet potatoes. When the method provided by the invention is utilized, a yield of stem tips can be increased by 20-30%, and a yield of the sweet potatoes can be increased by 15%-25%; the planting method is simple and easily accepted by farmers; and planting is performed by adopting the manner of three rows of the vegetable sweet potatoes and a line of the oil sunflowers, so that complementarity of a growth space and growth cycle of the crops is fully utilized, an occupied cultivated land area is relatively small, and planting of the oil sunflowers in a north-south direction can provide proper shading for the vegetable sweet potatoes.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a vegetable sweet potato cultivation method for oil sunflower interplanting. The method can make full use of the land's light, hot water and air conditions, improve the multiple cropping index, and uphold mutual benefits without harm and high economic benefits. In principle, increase the output value per unit area. Background technique [0002] Vegetable sweet potatoes are fresh and tender stems and leaves about 15cm below the top growth point of sweet potato vines, which are used as vegetables. They have the characteristics of tender taste and good palatability. Vegetable sweet potato has high leaf yield and long growing season, and its cultivation is not limited by seasons. In the season when high-temperature vegetable varieties are in short supply, vegetable sweet potato, as a new type of vegetable with better taste, can be used as a substitute fo...
