Prickly-colored peppers in greenhouse cultivation techniques

Color sweet is a kind of high-end quality vegetable that has emerged in recent years. It has six colors: red, orange, yellow, green, white and purple. The fruit is large, single fruit weight is 150-200g, and the largest fruit weight is 400g. It is colorful and beautiful in appearance. Generous, popular with consumers, can be used as high-end hotels, restaurants, dishes and gifts to share, can also be used for fruit, salad or cooking and other food, has a broad market prospects for development. I planted in a greenhouse for 2 years and carried out a large-scale development. We achieved a good harvest of both yield and profit. The output of 667m2 was over 5000kg and the yield was over 20,000 yuan. The cultivation techniques were as follows.

1, species selection

In order to adapt to different consumer demands such as high-end hotels, restaurants, dishes, and gifts, several varieties should be selected to make various colors complete. The brief introduction of each variety is as follows.

(1) The square fruit of O.O.O.O., when the fruit matures, the color changes from green to bright yellow, and the pulp is thick and hard. The average fruit height is 10cm, and the width is 9cm. The average fruit weight is 150g.

(2) Orange and West Asia's four ventricles, square fruit, matured from light green to bright orange, average fruit height, width 11cm, average fruit weight 200 g.

(3) White notarized square fruit, which has a strong fruit setting, is milk white after fruit setting, and bright yellow afterwards. It is a new development of the existing color bell pepper varieties with an average fruit weight of 220g.

(4) Zigui people quickly turned to purple after fruiting and their growth potential was strong. The average fruit weight was 150g.

(5) Monia grows strong, has few branches, is cold-resistant, hard-boiled, and flesh-thick. It is easy to store and transport. When it matures, it has dark red color, even coloration, and the fruit is square and medium to large.

(6) Jade pepper fruit lantern-shaped, slightly pointed at the bottom, the fruit from light green to light red, shiny fruit surface, beautiful appearance, thick flesh, high fruit set, more heat-resistant.

2. To cultivate age-appropriate seedlings

(1) Build nursery beds and cultivate nutrient soil, choose landforms with high dryness and can fill irrigation plots as seedbeds, build medium-to-large arch sheds or use solar greenhouses, raise seedlings in early August, use shelter film to prevent rainstorms, and shade nets Shade cooling, around the application of insect pest control. Seedlings are 1.5m wide and 15cm deep, and the bottom should be flattened. It should be solid and can be arranged on the bricks, which is conducive to daily management. 6 parts of fertile garden soil taken out and 4 parts of organic fertilizer are sieved and mixed. 1-5 kg ​​of N, P, K ternary compound fertilizer, 50-60 g of phoxim and 80-120 g of carbendazim per m3 of mixed soil are used. With nutritious soil filled with nutrients, into the seedbed, should be tight and seamless, soaked in water one day before sowing, ready for broadcast.

(2) Before cultivating seedlings, 10% trisodium phosphate is soaked for 20 minutes (minutes) to passivate the virus, then the seeds are soaked in warm water at 30°C for 6-8 hours, and then germinated at 25-30°C. After dew-whitening or sowing, sow one seed per seedling, cover and sieve fine dry soil 0.8-1cm thick, cover the film after sowing, before the seed is unearthed, cover the shed film, reduce the temperature of eucalyptus, and remove the odor in time. Grass, and application of 20% Confodic EC 2000 times plus 20% virus A wettable powder 500 times concentrated spray, control of aphids and virus diseases.

3, colonization

667m2 of arable land is applied to 10-15m3 of decomposed chicken manure, spread 50-80kg of compound fertilizer, and the land is to be leveled and ploughed deeply. The shed film is affixed 10 days before planting and the greenhouse is covered with high temperature. Since the color pepper grows strong, the plant is tall. Density 2000/667 m2, size and row, large row spacing 85cm, small row spacing 65cm, ridge height 20cm, furrows in large rows, ditch or acupuncture points in the ridge, concentrated into the cooked cake fat 400-500kg, and soil Mix well, plant spacing 45cm, one plant per hole. Do not disperse earthworms when planting so as to prevent root damage, cover the mulch, seal wells and membrane edges.

4. Management in Shed

(1) Warm water fertilizer management

After planting, until the seedlings are generally not watered, the greenhouse is raised to promote hairy roots. In this period, the temperature should be controlled at 26-30°C and the night temperature is 16-18°C. Afterwards, open both sides of the mulching film to carry out cultivating loose soil, shallow ridge ridge back, deep ridge and furrow, enter the flowering period, the temperature gradually decreased, should do a good job of temperature adjustment and lightening, in early November to early December Late cover, reaching temperature 25-27 °C, night temperature 15-17 °C, a temperature difference of about 10 °C is more ideal; December to next January is the coldest season, this period should be done to prevent cold and cold work, grasshoppers Appropriate late exposing and early-covering, conditional persons may hang a reflective screen on the back wall to improve lighting in the shed. Suddenly, after continuous cold weather, it is not possible to expel squats. Instead, it should be gradually removed. If wilting occurs, management should be conducted until the plants return to normal. After the cold has flowed, it is sprayed with 1000-1200 times of plant power 2003 fluid, which has good effects on plant growth and development and post-disaster reconstruction. If there is water shortage in the deep winter season, small water should be poured, and flooding should not be allowed. When the starter peppers begin to inflate, topdressing DAP 20kg/667m2. After entering mid-February, the climate is warming, and the ventilation volume is gradually increased. In combination with 667m2 furrows, 1,000kg of dried manure or 50kg of compound fertilizer is applied and watered in parallel. The results of the general period of 7-8 days pouring a water, the interval of a water application of urea 20kg/667m2 conducive to the color of the bell pepper, a uniform, colored pepper root distribution, root undeveloped, fertilization to master a few times to prevent burning root, Watering masters the principle of seeing and seeing wet to prevent rooting.

(2) Fruiting and fruiting

The production of color peppers should take quality as the top priority, and its growth potential is strong. It does not harmonize vegetative growth and reproductive growth, and it has to take advantage of the great fruit to take pruning measures. Most of the bell peppers are divided into double or triple branches, and the pruning starts from the second branch, that is, its outward lateral branches retain 2-3 leaves and 1-2 flowers topping, leaving as much fruit as possible. Keep the double stalks or three stalks growing upwards, and apply slings to prevent breakage and improve permeability. After growing for a period of time, remove small fruits that have hardened and have no potential for development, and remove teratogenic fruit as soon as possible.

5, harvest

The fruit is full of hypertrophy, the skin color is thick, and the peel is hard and shiny. When harvested, the fruit is large and the fruit stems are thick. To prevent breaking the stems, the fruit stems are cut with scissors, and the gift box or plastic is layered and arranged after harvesting. Bags are available for sale.

6, pest control

The color sweet peppers are mainly used to control aphids, virus diseases, and epidemics. The seedlings are treated with net 10g or 20% Kangfuduo 2000 times for locusts at the seedling stage. After planting, 40% Dimethoate EC 800-1000 times spray can be used to spray 30%. Insect cockroach net smoke agent 350g/667m2 fumigation anti-cockroach; use 20% virus A wettable powder 500 times liquid, 1.5% plant disease spirit 1000 times liquid to prevent virus disease; epidemic disease with 64% antivirus WP 500 times spray or 72.2% Preclosure 800 times liquid to irrigate the roots, etc.
