Can pepper be intercropped with corn?

I. Botanical and Biological Characteristics

1. Botanical characteristics: This variety has strong plant growth, developed root system, compact plant type, plant height of about 70cm, spreading degree of 60cm, double branches and highly concentrated fruits. This kind of fruit has a long horn shape. When ripe, it is dark red, shiny, high in oil content, about 16cm in length and 2cm in diameter. The fresh weight of a single fruit is 8-9 g, and the dry pepper rate is about 20%. Each fruit contains 70-80 seeds. It likes dryness and waterlogging, and the whole growth period is about 180 days. Mid-early maturing varieties, antiviral diseases and viral diseases.

2. Requirements for environmental conditions

Temperature (1) This variety likes temperature, the temperature range of the whole growth period is 12 ~ 30℃, and the suitable temperature for seedling stage is 25 ~ 28℃ during the day and 15 ~ 17℃ at night. During the flowering and fruiting period, the optimum temperature is 25 ~ 28℃ during the day, 16 ~ 20℃ at night, lower than 15℃ or higher than 35℃ will affect pollination and fertilization. The daytime temperature is 25 ~ 28℃, and the nighttime temperature is 65,438 05 ~ 65,438 08℃ during the full fruit season. It is beneficial to reduce the temperature at night and keep the temperature difference of 9 ~ 65,438 00℃.

(2) The root distribution of this variety is deeper than other varieties, and it is more drought-tolerant, but it is not waterlogged, and waterlogging in the field is easy to cause root suffocation and death. The suitable air relative humidity is 55% ~ 75% to avoid high temperature and heavy rain.

3. This variety can blossom and bear fruit early under the short sunshine condition of 10 ~ 12h, and its light saturation point is 30,000 lx. Avoid direct sunlight on the fruit surface during flowering and fruiting, otherwise sunburn and virus disease will easily occur under strong light, which is suitable for intercropping with tall crops.

4. Soil fertilizer should be planted in loam or sandy loam with high dry terrain, convenient irrigation and drainage, deep soil layer and rich organic matter. Generally, 0.25 kg of pure N and 0.08 kg of P2O5K2O0.31kg K2O should be absorbed from the soil per 100kg of red pepper.

Second, the climate characteristics and yield level of the introduction area

1. Introduction areas and climate characteristics are mainly introduced and cultivated in Yuanping, Daixian and Xinzhou, Shanxi. This area is located in the north-central part of Shanxi Province, with an average elevation of about 900m, east longitude 1 10 ~ 13, and north latitude of 38 ~ 39.5. The annual average temperature is 7 ~ 8.5℃, the hottest month average temperature is 23 ~ 24℃, there are 2 ~ 4 days of high temperature every year, the highest temperature is 37.8 ~ 40.4℃, and the annual average temperature has a daily range of 10 ~ 13℃. When the daily average temperature is stable ≥ 10℃, the accumulated temperature is 3200 ~ 3370℃, and the duration is about 170 days. The frost-free period is about 150 days. The annual sunshine hours are 2650 ~ 2850 h, and the annual average precipitation in this area is about 450 mm The climate is characterized by abundant sunshine, superior heat conditions, large temperature difference between day and night, and simultaneous rain and heat.

2. Introduction and planting situation and yield level. Two gold bars of pepper were introduced into this area. 1997, planted 2hm2 in Yuanping Yuanyang Fruit Farm. The soil is sandy loam, and the average output of dried peppers is 270kg/667m2, and that of fresh peppers is1400kg/667m2. 1998 planted 4.6hm2 in Xiahehe, Shi Cun and Wangjiazhuang in Yuanping, with an average of 3 10kg of dried pepper and 0/700 kg/667 m2 of fresh pepper. 1999 was planted in Xiahehe Village, Shangfeng Village and Xiamenwang Village in Daixian County, with an average yield of 350kg/667m2 for dried pepper and 0/900kg/667m2 for fresh pepper. In 2000, 400hm2 was popularized in Yuanping, Daixian and Xinzhou, and the average yield of dried pepper was 3 10kg/667 m2, which was equivalent to fresh pepper 1700kg/667 m2. 200 1, the planting area has developed to 800hm2, and a bumper harvest is in sight.
