Abstract

The invention discloses a method for planting sunflowers before sowing and multiple sowing of peas. The main steps are to plant peas on the sunflower reserved row empty film at the same time when preparing to plant sunflower fields in early spring, and the planting time is March 20. Around 12:00, the first ten days of May, peas are watered first, combined with watering and top dressing, sunflowers are planted in the reserved rows at the end of May and early June, and peas are harvested at the beginning of July. Generally, the yield of peas per mu is about 200 kg, and the yield of sunflowers basically does not decrease, which can reach 250 kg. about. The present invention is a high-efficiency three-dimensional planting technology developed for the Hetao irrigation area, which has more than one season and less than two seasons. It has the advantages of making full use of light, heat and soil resources, realizing two crops in one season, reducing surface exposure, and preventing sandstorms. The planting method has the dual functions of increasing production and income and protecting the ecological environment of the farmland, and has strong practicability and broad application prospects.

Description

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

technical field

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

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. Therefore, it is particularly urgent to study the rational use of cultivated land before sowing sunflower in this area to increase farmers' production and income, and to prevent wind erosion and desertification of farmland soil in spring. Through the promotion and continuous improvement of integrated technology, it is necessary to plant sunflower planting technology for short-term cold-resistant and fast-growing peas before sowing and multi-sowing.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for planting sunflowers before planting and re-sowing peas. The method is to plant peas when fertilizing the film in early spring on the fields for planting sunflowers, and reserve sunflower planting rows on the film at the same time. , The pea planting time is around March 20. The first water is poured on the peas in early May, and 15-20 kg of urea per mu is combined with watering. Sunflowers are planted in the reserved rows from the end of May to the beginning of June, and the peas are harvested in early July. At this time, the sunflower plant height is only about 15 cm, and the growth is basically not affected.

The technical problem to be solved in the present invention is realized by the following scheme: a planting method for sunflowers and peas before planting, which is characterized in that: from March 20th to March 30th, peas are sown with a wide-film seeder, sowing and fertilization 1. The mulching is completed at one time, using a mulch film with a width of 1.6-1.7 meters, the middle to middle of the mulch film is 1.8-2.0 meters, and 10-20 kg of seed fertilizer DAP per mu, and 3 rows of peas are planted in the middle of the film, with a row spacing of 30-35 cm, hole spacing 20-30 cm, 4000-4500 holes per mu, 3-6 seeds per hole, no seedlings after emergence, first watering of peas in early May, combined with watering, topdressing urea 15-20 per mu Kilograms, sunflowers are sown from May 30 to June 10, planted at 5 to 10 cm from the edge of the film, 30 to 35 cm away from peas, 30 to 35 cm apart from sunflowers, 2000 to 2500 seedlings per mu, two films The row spacing of sunflowers is 50-60 cm. It is estimated that the output of sunflower will be about 250 kg, and that of pea will be about 200 kg. The present invention is a high-efficiency three-dimensional planting technology developed for the Hetao irrigation area with more than one season and less than two seasons. Pea is a high-quality leguminous crop, which can be used as food and feed, and has a great market development prospect.

The advantages of the present invention are: the technical advantages of intercropping sunflower with peas are as follows: one is to make full use of the sowing dates of the two crops, stagger the growth season, and prolong the production period. Peas are harvested before July 10, and the symbiotic period with sunflower intercropping is only about 30 days , there is basically no symbiotic contradiction. Sunflower is equivalent to a single species, which improves the utilization rate of light, heat and soil resources, realizes two crops in one season, increases production and efficiency. Second, the input cost is low and the output is high. Peas have low input costs and high yields. Peas not only do not require high fertility but also have nitrogen fixation, which can fertilize the soil, improve soil properties, facilitate the later growth of sunflowers, reduce diseases, and achieve cost savings and efficiency gains. The third is to reduce the exposed surface in spring, which can effectively prevent the occurrence of sandstorms. Fourth, pea is a high-quality leguminous crop with great market development prospects. It is needed in fresh food, food processing, sprout seed preservation, high-protein feed for livestock and poultry breeding, etc. It can completely develop into an emerging industry that can increase farmers' income.

Detailed ways

Around March 20, peas were sown with a wide-film seeder, and sowing, fertilization, and mulching were completed at one time. Use 1.6 to 1.7 meters of plastic film, the middle to middle of the film is 1.85 meters, with 15 kg of seed fertilizer diammonium phosphate per mu, plant 3 rows of peas in the middle of the film, the row spacing is 33 cm, the hole spacing is 26.6 cm, 4177 holes per mu, each hole 3 to 6 seeds, no thinning after emergence. In the first ten days of May, the peas are poured with the first water, combined with watering, 15-20 kg of urea is applied per mu, and the sunflowers are sown from May 30 to June 10. The plant spacing is 33 cm, the seedlings per mu are 2245, and the row spacing of sunflowers between the two films is 55 cm. It is estimated that the output of sunflower will be about 250 kg, and that of pea will be about 200 kg.
