General use of sowing, per 667 square meters of spring sowing for 0.75 ~ 1kg, summer sowing for 2 ~ 2.5kg, autumn sowing for 1 ~ 1.5kg. spring sowing in late February to late March; summer sowing in late July to mid-August; autumn sowing in early September to early October. Strive for uniformity when sowing, after sowing with the foot will be gently trampled on the bed once, so that the seeds and soil in close contact, in order to facilitate the seeds to absorb water, early emergence. If the summer and fall period with the year harvested new seed sowing, because the seed is not yet out of the dormant period, need to fall to sprout. Therefore, summer sowing often put the seeds in 2-7 ℃ low temperature (refrigerator), germination before sowing.

1, seed collection

Wild caper can be divided into plate leaf type and flower leaf type according to leaf type, can choose different types of planting according to cultivation season. When first planting shepherd's purse, the seeds can be harvested from wild shepherd's purse plants growing in the field, and harvested in time after the wild shepherd's purse seeds mature in the summer and fall seasons, the wild shepherd's purse seed pods will rupture after maturity, so it is necessary to pick them in advance, together with the pods dry and store them in the sun, and choose the robust, disease and pest free plants to pick the seeds.

2, sowing time

Spring in February-April sowing, early spring when the temperature is low can be covered with plastic film, after the emergence of seedlings to uncover the film, or with a small arched greenhouse heat preservation, this season planting of wild shepherd's purse is suitable for selection of moss late in the flower and leaf varieties of shepherd's purse planting.

Summer in June-August sowing, this season the weather is hot, must take shade shed cooling and prevent rainstorms wash, this season is suitable for selection of plate leaf type wild caper varieties planting.

Late fall in September-October sowing, with flower leaf type or plate leaf type wild caper varieties can be planted.

3, the ground sowing

Cultivation of shepherd's purse mainly choose less weed plots, deep plowing more than 15 cm, do not apply basal fertilizer, this is because shepherd's purse seed is relatively small, if the contact with the fertilizer will affect the germination of the seedling. Planting land made into 200 cm wide beds, rake flat and fine, and then sowing. Shepherd's purse seeds are relatively small, in order to sow evenly, when sowing the seeds, add 1-3 times the fine soil mix evenly and then sow. Hot summer planting caper, in order to prevent high temperature, drought, seedling emergence difficulties, after sowing to cover with a shade net, in order to reduce the ground temperature, keep the soil moist.

4, field management

Weeding: caper plant is young, and the use of sowing, weeds and caper mixed growth, weeding is more difficult, in addition to strengthening the artificial weeding, you can use herbicides before sowing to reduce the growth of weeds.

Watering: watering after sowing and during the growing period should be sprayed with fine water, avoiding heavy water irrigation, in order to prevent soil crusting, seedling emergence. Seedling watering once a day in the morning, pay attention to watering can not be watered thoroughly, only light watering hard watering to keep the soil is not too dry and too wet on it.

Fertilizer: when 2 true leaves appeared to chase the application of clean animal manure, and later according to the growth of chestnut decided to chase clean animal manure or urea. Harvest 7-10 days before the pursuit of a more concentrated manure water, every harvest after the pursuit of fertilizer once.

5, pest control

The pests and diseases that harm the caper are mainly downy mildew and aphids. You can use 75% Chlorothalonil wettable powder 500 times liquid for spraying to control mildew. Use 40% Rogaine 1500 times liquid or 80% dichlorvos 1000 times liquid control.

6, harvest

Capsicum plants with 10-13 true leaves can be harvested, fall sowing capsicum generally 35-50 days can be harvested, can be harvested 3-5 times, each acre can produce 2500-3000 kg. It can be harvested 3-5 times, and can produce 2500-3000 kilograms per mu. Spring sown capers generally harvested 1-2 times, per mu yield of about 1000 kilograms. Harvesting capers with a knife, try to pick big and leave small.

Retained seed cultivation in October sowing, the next spring flowering pods, in the seed pods turn yellow when harvesting, drying and threshing.
