Introduction to Shepherd's Purse Growth

Shepherd's purse has very strong vitality, so there are three main places where it grows: beside ditches in fields, in rice fields, and beside small rivers. It is distributed throughout the country and is cultivated in Jiangsu, Anhui and the suburbs of Shanghai.

Shepherd's purse growth cycle

Shepherd's purse has strong adaptability. Its growing period is about one month. It grows vigorously, is relatively resistant to low temperatures, and has no strict requirements on humidity. Moist soil can improve the quality and yield of stems and leaves. It has strong adaptability to light and requires long days during the flowering and fruiting period. The soil suitable for its growth is clay loam that retains water and fertilizer.

Growth rate of shepherd's purse

The growth process of shepherd's purse is divided into bud stage, seedling stage, rosette stage, organ formation stage and mature stage. It grows fast. It takes 30-40 days from the first leaf ring to the second leaf ring at room temperature. It usually takes 20-30 days from the emergence of true leaves to the formation of the first leaf ring under suitable temperature conditions.

Shepherd's purse growth cycle management

The yield per mu of shepherd's purse under conventional cultivation is about 1,400-1,600 kilograms. It has a short growing period and can be sown once and harvested multiple times through artificial cultivation, providing a year-round supply.

Temperature management : When the temperature is too high for shepherd's purse planting, set up a shade net for cultivation, uncover it in the morning and evening, and cover it at noon to lower the temperature. It can sprout at 5°C. The suitable temperature for growth is between 12°C-18°C. Growth is hindered under high temperature, it is not easy to sprout, and it is easy to bolt.

Fertilization management : The management of shepherd's purse fertilizer is mainly topdressing, and the types of fertilizers are mainly nitrogen fertilizer and dilute human feces and urine. The principle is light topdressing and frequent topdressing. The growing period of spring-sown shepherd's purse is shorter, and generally two topdressings are applied. The growing period of autumn-sown shepherd's purse is longer. When adopting three-harvest cultivation methods, topdressing should be done after each harvest.
