You can eat original shepherd's purse at home all year round. Homemade dehydrated shepherd's purse can be directly soaked in boiling water. The color and nutritional value remain the same, not only is the aroma stronger than fresh vegetables, but it is also more convenient to store, transport and pack. Shepherd's purse is a popular vegetable, but the shelf life is too short. Generally speaking, we can only eat fresh shepherd's purse in early spring and early autumn in three or four months. What should I do after the trial period ends? Don't worry, we're bringing it today - dehydrated shepherd's purse that tastes like a fresh vegetable when soaked. The key is to take good care of it.

The selection of plots for deep-spotting yam is a tuber crop. The tubers are deeper in the soil, and they are resistant to drought and drought. They like deep, loose soil. Therefore, it is necessary to choose high-desert and well-drained sandy soil. In view of the irritability of yam, it is best to make it once every two years with the grass crop, which can effectively reduce or avoid the occurrence of diseases. Before the soil is frozen in the autumn, the planting trench is dug by 70-80 centimeters, and the depth of the trench is 100 centimeters in width and 25 centimeters in width, and the excavated raw soil and mature soil are respectively placed on the ravine. The stones and brick blocks encountered during trenching should all be picked out so as not to cause damage to the yam tubers. After a winter and spring, the soil was fully matured and the pathogenic pests were frozen. In the early spring of the following year, combined with Shiji Fei, backfill the soil into the ditch, fill the raw soil first, and then fill in the mature soil. Once each step is 30 centimeters thick and step on the foot to prevent collapse of the planting ditch.
Select good seed base fertilizer
It is necessary to use varieties that are suitable for local planting, large potential for yield increase, and high quality to lay the foundation for the high yield and quality of yam. The growth period of yams is long and requires a large amount of fertilizer. The ratio of nitrogen, phosphorus and potassium is 4:1:5. If fertilization can be measured, the effect will be better. First, the basal fertiliser was applied, and 3,000 kg of high-quality organic manure was decomposed and mixed with 100 kilograms of Sarkozy compound fertilizer and applied in a soil layer of 25 cm or less. Because yams are hi potassium and chlorine crops, if chlorine-containing fertilizers are used, tuber yield and quality will decline, and they will be difficult to store and transport. Therefore, avoid using chlorine-containing fertilizers and pay attention to increasing potassium fertilizers. After the fertilization, a large amount of water is poured along the ditch, and the soil is loosened and warmed at the right time after irrigation to lay the foundation for seedling preservation.
Timely sowing cover film
Yam hi warm, intolerance to frost, sowing temperature is too early, prone to bad species. However, the growth period of yam is about 180 days. Sowing the evening will reduce the yield and quality. The seeding is usually done at a stable temperature of 5°C at 14°C. The time is about mid-April and the latest at the end of April. One month before sowing, the outdoor leeward sunny place was selected for germination. Sowing in the sun for 3-5 days before sowing, then soaking for 4 minutes with 40% carbendazim gel suspension 300 times, remove and dry. When ditching sowing, ditch depth 7-10 cm, along the ditch Mushi phoxim granules 2-3 kilograms, can control lice, cockroaches, tigers, wireworms and other pests. In the area where nematode disease occurs, avermectin granules are applied along the gutter, and 5-10 kilograms per mu. After sowing the soil, cover it with a 1.2 m wide plastic film. The mulching film has the function of warming and protecting the earthworms, and it can grow 4-6 days earlier and increase the yield by 10%-20%. In order to prevent damage to weeds, after the film is leveled on the ground, herbicides to control grasses and broadleaf weeds are sprayed once again.
Strengthen the management of high yield and quality
Membrane breakage after the emergence of seedlings in time to break the membrane, when half of the seedlings exposed on the ground, seedling height 20 cm, it would be scaffolding.
When the amount of growth of stems and leaves in the seedling stage of top dressing of yam is small, and the base fertilizer is sufficient, it is generally not necessary to top-dress. Before and after the mid-June, the vines will be thrown into a tree, requiring more fertilizer, and the first fertilizer application will be carried out. Mushi Spreadable Compound Fertilizer (30 kg) will be used to promote the growth of stems and leaves. From late July to early September, it is the period of tuber enlargement, which is also the peak season for fertilizer. In the middle and late July, 30 acres of canyon and 10 kg of potassium sulfate are scattered. In order to protect the roots of the leaves and promote the growth of tubers, extra-root dressing after late August can increase production by 15%. Each tuber of tuber inflated with 20 ml of water and 50 kg of water per acre was sprayed on the leaves, sprayed once every 7-10 days, sprayed 2-3 times, or sprayed with 0.3% potassium dihydrogen phosphate solution 2-3 times. Combining the soil with topdressing and cultivating the soil for 2-3 times will not only facilitate drainage but also facilitate tuber growth.
Watering Drainage Yam is a drought-tolerant crop. Even if it is dry during the early growth stage, watering is generally not required to promote downward growth of rhizomes. However, more water is needed during the tuber enlargement period, and the soil should always be kept moist and watered in case of drought. In the event of rain, it will be ruled out as soon as possible to prevent the formation of a ditch and cause diseases, which will affect the growth of tubers.
Removal of yam bean yam bean during the growth process consumed a large number of nutrients in the plant body, seriously affecting tuber enlargement. According to the experiment, timely removal of yam bean will increase tuber yield by 15%-20%.
Yam sowing period to scratch production
With people's growing awareness of health care, yam, a dual-use agricultural product, has become increasingly popular. If properly managed, the income per mus of yam is not difficult. The present sowing date is coming. The peasant friends who are interested in planting yam must prepare their production materials in advance and grasp every management details from beginning to end to ensure a bumper harvest.
