Intercropping maize with corn is based on the fact that the yield of corn has not decreased, and the cucumbers of summer and autumn of the first season have been increased to meet the market demand for low-season vegetables to achieve high yield and high efficiency. Planting specifications Around June 20th, the big corn lined up 2 rows of small ridges, planted 2 rows of cucumbers, cucumber spacing 40-45 cm, plant spacing 25-27 cm, and 2500 acres planted. Variety selection of corn to use a large number of large ear, single plant high yield potential varieties. For cucumber, according to the characteristics of summer and autumn climate, choose adaptable, disease-resistant, heat-resistant, resistant varieties. The roots of the cucumber planted in the site preparation are weak, and more organic fertilizers such as decomposing ring fertilizer and compost should be applied. In general, 2500 kg of soil-fertilizers and 10 kg of diammonium phosphate are used in Mu. High-ridge cultivation, ridge height 10-12 cm, furrow width 20 cm. Seedings are broadcast live in the open. In order to make the cucumber sprout quickly, soak the seeds for 3-4 hours before sowing, so that they can be sown after sowing. When sowing, plant the rows on the ridge to open the ditch, water the ditch and wait for the water to infiltrate. Put 25 cm seeds on the ditch and put 2-3 seeds on each ditch. Then seal the ditch and smooth the surface and water the ditch to keep the soil moist. Seedling management When the first true leaves of the cucumber are revealed, it takes time and seedlings to leave a strong seedling at each pier. By the time of the second leaf, combined with the spraying of disease prevention drugs (chlorothalonil, Rhizoctonia, etc.) plus 0.3% -0.5% of urea to promote seedlings robust growth. Such as lack of fertilizer, plant growth is slow, can be in the 3-4 leaves, topdressing a quick-acting nitrogen fertilizer, topdressing urea 4 kg per mu, chasing after watering, and timely cultivator loose soil. Before and after the first female flower of cucumber is opened, watering is strictly controlled to prevent stems and leaves from affecting the melon. When the cucumber grows to top dressing. Decomposition of dried manure can be applied, with about 500 kilograms per mu. Fertilizer should be thoroughly mixed with the soil, and the cover soil should be compacted. In addition, in order to supplement the potash fertilizer and improve the quality of the cucumber, weeding can be applied to the planting ash in the furrow with watering, 100-150 kilograms per acre, and after the application, we can paddy and water. The management period of the melon period is the high temperature season. The watering should be carried out in the early morning or early evening. Do not water it when it is hot in the middle of the day. Usually, pour water once every 2-3 days. After a thunderstorm, it is necessary to flush with irrigation water to cool down. After the heavy rain, it is necessary to clear the drainage channels in time so as not to flood the fields. Summer and autumn cucumber topdressing should adopt the method of less application and diligence. Generally, every time it takes 2-3 times to recover one fertilizer, each application of 3 kg of urea or flushed manure and urine. Disease Prevention and Control Summer and autumn cucumbers are in high temperature and humid conditions, and are prone to various diseases. Therefore, we must do preventive work (especially during the rainy season). Cucumber from the plant to receive alternately spraying chlorothalonil, carbendazim, Rhizoctonia, etc., the seedling concentration is small, the late concentration.
