Can carrots be interplanted with small red peppers in autumn?

Carrots can't be interplanted with red pepper in autumn, but garlic can be interplanted with pepper.

1, select the appropriate variety. In order to ensure the high yield and high efficiency of the two crops and stagger the time to market, two varieties of garlic were selected, one is "hybrid garlic seed" with high garlic yield and early bolting, and the other is "Cangshan stupid garlic" with high garlic bolting yield and good quality. Pepper is selected from the local farmers' self-selected variety "Li Guan Pepper", with slender fruit shape, special spicy taste, high temperature resistance, waterlogging resistance, strong stress resistance, easy sun exposure and high drying rate.

2. Choose the appropriate interplanting mode. In order to give consideration to the high yield of garlic and pepper and facilitate the interplanting, most garlic beds are 60-80 cm wide, with 4 rows of garlic planted in each bed, the row spacing is 7-10 cm, and a ridge between two beds is 20-25 cm wide and 15 cm high, which is regarded as

Pepper intercropped on the ridge between two ridges, forming a pepper intercropping mode with row spacing of 80 ~ 100 cm and pier spacing of 30 cm.

3. Technical measures for high yield and high efficiency of garlic.

① Selecting land and applying sufficient fertilizer: The above nine villages are all black clay with medium and high soil fertility and high terrain, and there is no water accumulation in flood season. In order to ensure garlic yield per mu 1500 ~ 1800 kg, farmyard manure 5000 ~ 7500 kg, ternary compound fertilizer 100 ~ 125 kg, potassium sulfate 25 ~ 30 kg, ammonium bicarbonate 100.

② Seed selection: Choose garlic with big head, even petals, "four or six petals" and no bruise. 5 ~ 7 days before planting, dry the selected garlic seeds for 2 ~ 3 days, and soak the chopped garlic cloves in clean water 10 ~ 12 hours before planting.

③ Suitable planting time: The suitable planting time of garlic in southern Shandong is from late September to 65438+10.5.

(4) Apply two fertilizers and five waters appropriately: after planting the whole field, apply garlic water once and overwintering water once before freezing. At this time, urea or ternary compound fertilizer 10 ~ 15 kg can be applied to the plots with insufficient base fertilizer, and all the fields without plastic film before and after Tomb-Sweeping Day are covered with grass, with urea 10 ~ 65438+ per mu. In early May, garlic entered the vegetative growth period and reproductive growth period, which is also the peak period when garlic needs fertilizer and water. At this time, it is necessary to water it in time and use water to promote its growth. In plots not covered with plastic film, after each watering, the ground should be hoed when the moisture content is appropriate. Cutting grass can not only eliminate weeds between ridges, but also loosen soil and conserve moisture.

⑤ Pay attention to the prevention and control of pests and diseases: The main disease of garlic is leaf blight. In addition to strengthening field management, from mid-April to early May, 0.25 kg of 25% carbendazim wettable powder can be added to 0.5 kg of urea and 100 kg of water for whole plant spraying, and 1 time every 7 ~ 10 days for 3 ~ 4 times continuously. You can also spray garlic Julia 500 ~ 600 times per mu for prevention and control. Pests are mainly garlic maggots. When preparing soil, 1 ~ 1.5 kg phoxim can be mixed into toxic soil, then ploughed into the ground, and other underground pests can be treated. When planting garlic, seed dressing with 0.5 kg seed coating agent per mu; In the rotting period of garlic, trichlorfon or dichlorvos can be sprayed 800 ~ 1000 times to control adult garlic maggots.

⑥ timely bolting and harvesting garlic: According to our observation for many years, the above two garlic varieties were planted in the autumn equinox in southern Shandong (late September), bolting in Xiaoman (middle and late May) and harvesting in mango (late June). The economic benefit, yield and quality of garlic bolts are closely related to the timely bolting technology. When the yield is the highest and the quality is the best, garlic bolts should be pulled in time. First, water should be stopped 3-5 days before bolting, and then bolting should be carried out around noon on sunny days. It is forbidden to pull out the flag leaves to affect the garlic's continuous expansion. Garlic is usually peeled 12 ~ 15 days after bolting. Pay attention to drying garlic after harvest to prevent mildew in the rain.

4. Technical measures for high yield and high efficiency of pepper.

① Cultivation of healthy seedlings: "Li Guan Pepper" is planted around Tomb-Sweeping Day in most years (from late March to late April). Soak the seeds in warm water at 60 ~ 65℃ for 8 ~ 10 hour before sowing, and then sow them in the sunny bed filled with nutrient soil. Nursery should be located in the leeward and sunny place. Qualified nursery should be built with east-west length of10 ~15m, north-south width of1.5 ~ 2m, north wall height of 40 ~ 50cm and south wedge pile height of 20 ~ 25cm. Before planting, fill in nutrient soil, level the border, and pour water evenly at the bottom. After the water seeps out, plant 5-7 grams per square meter. After planting, cover 1.5-2 cm of nutrient soil, sprinkle rodenticide on the soil, and then fix the plastic sheet on the scaffold. Cover the plastic sheet with 5 cm thick straw and cover it at night. After the seedlings come out, we should master the temperature and humidity of the seedbed flexibly according to the situation of the seedlings and the weather. When planting in Xiaoman, the seedling age should reach 60-70 days, and the plant height should be 20-25 cm, so that the buds are free from pests and diseases.

② Appropriate interplanting and reasonable close planting: Generally, pepper should be interplanted immediately after pulling garlic bolts in late May, with row spacing of 800 ~ 100 cm and pier spacing of 30 cm, with 3 ~ 4 plants per pier and 2,800 ~ 3,000 piers per mu. After interplanting, it must be watered once with planting water to promote its early slow seedling growth.

③ Timely control of pests and diseases: use 1500 times omethoate to control aphids and cotton bollworms, and control virus diseases in the whole growth period.

④ Harvesting dried peppers in time: According to our observation, "Li Guan Pepper" was sown on March 22nd, May 25th, pepper germinated in June 15, blossomed on July 5th, changed from green to purple in August, and was picked and dried when it was bright red in August 14. During the whole growing period, as long as the field management is strengthened and the flood season is not destroyed, red fruits can be picked and dried in stages. Pull out the whole plant before the arrival of severe frost to prevent freezing injury.

Existing problems and countermeasures

Due to the long cultivation time and large continuous cropping area, the following problems were found in the investigation, which should be paid attention to.

1, garlic leaf blight and garlic rice blast are getting worse year by year, and comprehensive control measures are still lacking at present.

2. Pepper virus disease is getting worse and worse. According to our field investigation in June 65438+August 65438+June 6996, the virus strain rate is as high as 20% ~ 30%, the leaves of infected plants are yellow-green and wavy, and the leaves of seriously infected plants roll up like clumps, which seriously reduces production. We should pay attention to strict disinfection of seeds to reduce the source of poison, prevent and control aphids and other virus-transmitting insects in time from seedling stage, and take effective spraying and comprehensive measures as soon as possible after planting.

3. The fruit moth is serious. According to the investigation, the fruit rot rate caused by cotton bollworm, tobacco budworm and other hazards is 8% ~ 10%, the eaten fruit falls off when it is young, and the damaged fruit becomes moldy in the rain. In the future, it is necessary to strengthen the prediction of fruit borers, seize the favorable opportunity before the incubation period of fruit borers and before larvae eat fruits, and spray pesticides skillfully.

4. The variety of pepper has degenerated. "Li Guan Pepper" has not been selected and rejuvenated for many years, so its leaves are varied, its plants are uneven, its fruit shape, length and thickness are very different, and its growth appearance is extremely inconsistent. In the future, Li Guan pepper must be systematically bred, purified and rejuvenated in a planned way.

5. In order to control the plant diseases and insect pests in garlic and pepper intercropping, we must implement the plant protection policy of "prevention first, comprehensive prevention" and adopt the strategy of small treatment, clever treatment and radical treatment, so as to achieve twice the result with half the effort.
