A kind of planting method of sunflower covering and re-sowing peas before sowing

Abstract

The invention discloses a planting method for interplanting pea before sowing of sunflower. The planting method mainly includes: when fertilizing and mulching a land block where sunflower is prepared to be planted in early spring, planting pea on line space films reserved for sunflower at planting time about 20th March; watering the pea for the first time in early May, and combining watering with fertilizing; planting sunflower in reserved lines at the time from the end of May to the beginning of June; harvesting pea at the beginning of July, wherein yield of pea per mu is about 200kg generally, and yield of sunflower is not reduced basically and can reach about 250kg. High-efficiency three-dimensional planting technology is developed according to the circumstance that a Hetao irrigation area is sufficient for one crop and insufficient for two crops, and has the advantages that light, heat and soil resources are utilized fully, one-season two-harvest is realized, ground surface exposure is reduced, and sand storm is prevented. The planting method has double effects of increasing yield and income and protecting ecological environment of farmland and is high in practicability and wide in application prospect.

Description

technical field [0001] The invention relates to a method for planting sunflowers for multiple sowing of peas, in particular to a method for planting sunflowers for multiple planting of peas before sowing. Background technique [0002] Sunflower is the main planted crop in the Hetao irrigation area in my country, and the sown area accounts for about one-third of the total cultivated land area. Most of the sunflowers are sown from the end of May to the beginning of June. Before sowing and at the seedling stage, sunflower planting fields have nearly 3 months of leisure time, which creates space-time conditions for planting fast-growing and cold-resistant crops. If the land is not used during this period, the land and light and heat resources will be seriously wasted. In addition, the frequency of strong winds in spring in northern China is relatively high, and large areas of exposed ground can easily induce sand and dust hazards, posing a potential threat to the environment.
