When is the pepper planted? When is the best time to plant pepper saplings

Due to the different geographical latitudes in various parts of China, the pepper cultivation season varies greatly. In southern China and southern Yunnan, peppers can be cultivated all year round, but the best time to grow is summer and autumn. Spring cultivation is sown and seedlings are sown from October to November of the previous year, the seedling period is 80-90d, planting is planted in January-February, and harvested in April-June; The summer cultivation and sowing period is from late January to early April, the seedling age is 60d, the planting period is from mid-March to early June, and the harvest period is from May to September. The sowing period of autumn planting is from July to September, the seedling age is 30-40 days, the planting period is from July to October, and the harvest period is from October to January of the following year.

In summer and autumn, peppers avoid high temperatures and cold weather, and can grow normally under open field cultivation conditions, so the yield is higher. In the single-main vegetable cropping areas of Northeast China, Mengxin and Qinghai-Tibet, the sowing period of pepper is generally from late February to early March, the planting period is mid to late May, and the harvest period is from July to September. In some areas where the purpose of cultivation is drying, it can be planted late so that the top fruit can ripen at a similar time. North China vegetable double main cropping area, open field cultivation in spring and autumn after two stubbles, spring early cultivation in the yangqi, greenhouse seedlings, planting after the final frost, summer market, sowing period in early January, planting period in late April - early May; After autumn, seedlings are sown in the open field from late April to late May, planted after the harvest of spring vegetables in the open field or after wheat harvest from mid-June to early July, and ** market from early August to late October; There are also many places, such as Zhangjiakou in Hebei Province, where a large season of open-field cultivation is carried out from spring to autumn.

The three main vegetable producing areas in the Yangtze River Basin include Sichuan, Yunnan, Guizhou, Hubei, Hunan, Jiangxi, Shaanxi and Chongqing, which are the largest pepper producing and consuming areas in China. Open field cultivation is generally sown in November and December of the previous year, planted in April, harvested in late May and mid-October, and the harvest period is as long as 6 months. The high temperature in July and August has a certain impact on the growth and development of peppers, but as long as the cultivation and management measures are appropriate, they can still flower and bear fruit normally.

In addition, in order to overcome the influence of high temperature and drought, typhoon and rain in southern China from July to September, the cultivation technology of alpine open field pepper was developed in the Yangtze River basin and South China, because the temperature dropped for every 100m above sea level, and the average temperature in the mountainous area at an altitude of 500-1200m was 3-6 lower than that of the plain, and the temperature difference between day and night was large, and the rainfall was more, which was conducive to the growth and development of pepper. It can be planted in the mountainous areas of the Yangtze River basin at an altitude of 500-1200m, and the mountainous areas with an altitude of 600-800m are the most suitable, with a long harvest period and high yield. Generally, it is sown from late March to early April, planted from late May to early June, and harvested from late July to October.

In South China, the altitude is below 500m, sowing from January to April, above 500m above sea level, sowing around March, and starting to market in July. In this way, the various growth and development stages of pepper are basically in suitable environmental conditions, and the harvest season from July to September is the autumn light period of pepper in plain towns, and timely harvesting is very beneficial to the regulation of the city.

Peppercorns are drought tolerant, and too much water can lead to poor pollination and delay fruiting. Pepper sowing period, seedling period, seedling stage, growth and development period requires soil weight moisture content in 15%-30%, if the water content of pepper growth period is less than 10%, it will lead to no flowering, no fruit, and even the death of the pepper tree, the dormant period (winter) of the pepper does not require high water and does not need to be watered. Derong County is a well-known drought center, the average precipitation over the years is meters, pepper sowing period, seedling period, seedling stage, growth and development period generally need timely water diversion irrigation (generally 2-3 days irrigation 1 time), and in the precipitation concentration of 7-8 months, when the precipitation is too much, should pay attention to drainage, otherwise it will lead to the death of pepper roots or the occurrence of pests and diseases, reduce the yield <>

Zanthoxylum trees are more drought-tolerant and waterlogging, so it is generally recommended that growers sow seedlings in the spring (mid-to-late March to early April) or before the soil freezes. The planting time in the north and south may be different, generally the climate in the north is colder, so choose to plant in the spring, which is conducive to seed germination, and in the south, sow seeds before the soil freezes, and do not need to cover the mulch film to keep the soil moist.

Derong County is located in the dry and hot valley area of the lower reaches of the Jinsha River, and its unique geographical location and climatic conditions make it a place"Peppercorn"The special production area, after thousands of years of genetic changes and long-term cultivation and breeding, has become a primitive local pepper variety in the county. I think the physiological environment of this pepper is so special and dry, so I think it should be able to survive whenever it is planted. And it also has a very high nutritional value, and I think this item species is a very good species to survive.

Derong pepper pepper has thin flesh, strong spicy taste, can be appetizing and spleen-invigorating, has high content of vitamin E, calcium, selenium vitamin C and riboflavin, and has high health care and pharmaceutical value.

The best season for planting pepper seedlings is winter or spring, the higher the survival rate when the weather is colder, and after planting, it is necessary to bury it with soil, put some grass on it, and then open it again when the weather warms up in spring, and the survival rate of water-like seedlings is the highest.

Most of the general planting time is best in autumn and winter, but for northern regions the general planting time is in the spring after the ground has thawed. The Central Plains region and the areas north of the Central Plains are generally most suitable for planting in autumn and winter.

The original name of the pepper tree: Sichuan pepper.

Aliases: big pepper, Qin pepper, Shu pepper.

Preferences: drought tolerant, sun-loving.

Function: Sichuan pepper can be used in traditional Chinese medicine, with pain-relieving, cold-repelling, and other effects.

The main varieties are: Dahongpao pepper, nine-leaf green pepper, and big red pepper.

Zanthoxylum pepper seedlings are planted in early spring.

After the soil thaws in early spring, the soil around the roots of the pepper tree is planed 30-50 cm deep, and about 30 kg of organic fertilizer is applied to each plant; At the germination stage in mid-April and after fruit picking in late July, each plant was applied with a standard kilogram of chemical fertilizer. After fertilization, water it thoroughly in time.

Zanthoxylum bungeanum trees are drought tolerant and barren, especially suitable for planting in terraced fields, marginal land, wasteland, and around orchards. Scientific planting of pepper trees is also an effective way to improve the ecological environment and increase farmers' income.

Zanthoxylum pepper seedlings are planted in spring in the south, and the climate in the north is cold in spring, and the soil is relatively dry, so it is more suitable for planting in autumn. Spring planting pepper trees should be selected in the area with sufficient rain, around the vernal equinox is the most suitable planting time, autumn planting, pepper seedlings are more tender in September and October, and the seedlings are older in August and September.

1. Spring planting in the southern region.

Planting pepper seedlings in the southern region is suitable for early spring, the best time is around the vernal equinox, the planting location should be selected in a hilly area with sufficient rain, or planted in a convenient irrigation place, planting pepper seedlings in spring is mainly required to have sufficient water.

2. Autumn planting in the northern region.

The spring in the northern region is still relatively cold, the soil is also very dry, and the rainfall is not much, so it is better to plant in autumn, if the pepper seedlings are older, planted in early autumn 8 to September, when is the best time to plant the more tender pepper seedlings, the time can be a little later, planted in September and October.

3. Prune before planting.

Generally, when the pepper seedlings are older, they need to be pruned, at this time the leaves of the seedlings have grown a lot, and after transportation and long-term placement, it is inevitable that there will be yellow and curly branches and leaves, and those yellowing and dry branches and leaves can be cut off, saving the water and nutrients of the plant to make it grow healthily.

Fourth, planting management.

Before planting pepper seedlings, the soil should be turned over first, and it is best to turn it deeper, which can make the soil more fertile, and then add some organic fertilizer as base fertilizer when planting. If there is often strong wind in the planting area, it is necessary to erect stakes next to the saplings to prevent them from being blown down, and irrigate them in time when the rain is insufficient.

Spring planting in southern China: Before and after the spring equinox, the planting site is selected in a hilly area with sufficient rain, or planted in a place that is convenient for irrigation, and the planting of pepper seedlings in spring is mainly required to have sufficient water. Autumn planting in the northern region:

In the northern region, the spring is still relatively cold, the soil is relatively dry, and there is not much rainfall, so it is better to plant in autumn; If the pepper seedlings are older, they can be planted in August-September in early autumn, and the more tender pepper seedlings can be planted in September-October.

Sowing comes from July to September when the seeds are fully mature, and the seeds are collected in the room in time after harvesting

Dry in the inner dry place, take out the zhi seeds after the peel is cracked, and store them after drying to prevent DAO from mildew and oil. In early March, the stored seeds were soaked in 70 water for 12 hours, and the wax layer on the surface of the seeds was rubbed off with alkaline water, and then washed with water and the wet sand was warmed to 20 to 20 to promote germination and storage. After mid-March, strip sowing begins after the seeds are exposed.

Generally, the row spacing of the plant is 3-5cm and 30-40cm, and it can also be sown in furrows. According to the moisture, it is necessary to sow seeds with sufficient moisture, and the thickness of the covering soil is 2-3cm. The sowing amount is about lokg mu, the germination rate is about 70, and the seedling yield is more than 50,000 mu.

According to different cultivation conditions, the planting period is selected according to local conditions. In general, it should be planted in autumn where there are no irrigation conditions; Where there are irrigation conditions, it is advisable to plant in spring.

Autumn planting, the sooner after the leaves have fallen and before late December, the better. Spring planting time is as long as the seedlings are before they sprout.

Before planting, determine the planting point according to the planned planting density of the plant row spacing, and dig a pit according to the point. Generally, the depth of the planting pit is 50-60 cm, the diameter is 50 60 cm, when digging the pit, the surface layer of 30 cm soil is stacked separately from the deep soil, and is mixed with the rotting farmhouse manure respectively, when planting, first of all, the deep soil mixed with farmhouse fertilizer is backfilled to the bottom of the pit, secondly, after the backfill, the seedlings are put into the pit after stepping on tightly, so that the root system is stretched, the topsoil is broken, covered in the roots, and the seedlings are gently shaken, so that the roots are not nested, and the soil is in close contact with the root system. The planting depth is 3-5 cm deeper than the original soil of the seedlings, and the tree tray is filled with enough water after planting, and when the soil is not in a mud state after water infiltration, the tree tray is sealed with soil to prevent cracks in the tree disc and reduce water evaporation.

The place where the water source is difficult should be planted in rainy days, before planting, the root system of the pepper seedlings should be slurred, that is, the raw yellow mud and water should be adjusted into a mud paste, and the roots of the pepper seedlings should be immersed in the mud, and then taken out to make it "collect water" and then planted.

For many years, I have purchased pepper, forsythia, diding, qingqiao, bupleurum (wild, domestic species) skullcap, salvia, hawthorn, wild yuanzhi, winter grass, lingfat rice, sour jujube, sour jujube kernel, pepper, walnut, atractylodes, locust rice, codonopsis, bellflower five plus peel (fragrant) and so on.

1. The collection and interception of cuttings, before the end of the sap flows in early spring, select young mother trees that are free of diseases and insect pests and grow robustly, collect 1 2-year-old pepper branches, cut them into 25 30 cm long cuttings, cut the upper end flat, and cut the lower end into a horse ear shape.

2. For cuttings treatment, tie the cuttings into bundles with a diameter of 10 15 cm, immerse them in 50 times aqueous solution of the chemical alphthalene acetic acid, and take them out after soaking for 24 or 48 hours.

3. Cuttings, on the whole seedling ground, according to the row spacing of 40 cm, plant spacing of 5 10 cm for cuttings, so that the cuttings are exposed 2 3 cm, and irrigated in time after being solid, and after the water seeps dry, the cuttings are covered with a layer of grass or 2 cm of loose soil. When there is a drought, irrigate to keep the soil moist.

4. The cutting time is carried out in early spring in February.
