Field management of shepherd's purse

Shepherd's purse is an annual and biennial herb of Cruciferae, and shepherd's purse is a popular wild vegetable. Because shepherd's purse has high nutritional value, it is a high-fiber vegetable, and its food fiber content is very high. It also has the effects of diuresis and hemostasis, heat-clearing and detoxification. However, with the mining of people, shepherd's purse also needs to be artificially planted to meet the market demand, but planting needs to have a correct management method. Let's take a look at the field management of shepherd's purse cultivation with Xiaobian.

1. Seedling management

The emergence speed of shepherd's purse is relatively fast, if nothing happens, spring sowing shepherd's purse can sprout normally in a week. Before emergence, the seeds should be properly watered to maintain the soil water content, which is beneficial to seed germination. After emergence, irrigation should also be done to prevent soil drought, but rainy weather should also pay attention to drainage. Drainage to prevent mud splashing on the vegetable leaves, if there is sputtering to pay attention to clean up, to prevent hindering the photosynthesis of vegetable leaves, affecting the growth. If it is autumn sowing shepherd's purse, it is necessary to control moisture, to prevent excessive moisture leading to shepherd's purse apprenticeship, do a good job in overwintering management.

2. Ploughing and weeding

Shepherd's purse plant is relatively small, nutrient absorption capacity is not strong, so weeds will pose a greater threat to the growth of shepherd's purse. And it is easy to grow mixed with weeds, which leads to the limitation of weeding work in the middle and later stage. Therefore, we should choose places with a small number of weeds to cultivate, and after cultivation, we should also do a good job of ploughing and weeding. Mid-tillage can not only effectively weed, but also improve soil permeability and promote the growth of shepherd's purse. The method of artificial weeding should be used as far as possible to prevent the growth of weeds from affecting the growth of shepherd's purse, and it is also very easy to hurt the root of shepherd's purse when weeding.

3. Topdressing in time

The growing period of shepherd's purse planted in the first half of the year is not long, but because the plant is short, there are still certain requirements for nutrition. During the growth period of shepherd's purse, fertilizer should be applied at least twice, starting when the seedlings grow 2-3 true leaves, and then again in about 2-3 weeks. Each time the fertilizer can be used mature farm fertilizer or urea, but we should pay attention to the concentration and amount of fertilizer to prevent shepherd's purse from growing or burning roots. The growth period of autumn sowing shepherd's purse is long, so the number of topdressing should be increased appropriately, in addition to topdressing during the growing period, it should be applied once for each harvest.

4. Timely harvest

The harvest time of shepherd's purse also has certain requirements, it can be harvested 1-2 months after sowing and emergence in the first half of the year, and generally can be harvested twice. The growing period of autumn sowing shepherd's purse is about a month, but the number of harvests is about 5 times. To observe the plants when harvesting, first harvest the plants with large leaves, dig out the plants with roots, and the small and medium-sized plants can continue to grow. And first of all, the plants that are too dense are harvested to ensure that the subsequent plants have enough space for growth. Timely watering and fertilization after harvest can promote the growth of unharvested plants and increase yield.

The above is a brief introduction to the field management of shepherd's purse planting. What we should pay attention to in planting is that the shepherd's purse plant is very short and almost all collapsed on the ground. Often mixed with a variety of weeds is difficult to distinguish, so we plant weeds in shepherd's purse is very important, we must pay attention to. That's all for today's introduction.
