In winter, intercropping during the "light period" is a common practice. For cruciferous vegetables, such as Chinese cabbage, it can be transplanted from a nursery or directly sown, with yields exceeding 2,500 kg per mu. Mustard, kohlrabi, and cabbage are typically sown in October and transplanted in November, ready for harvest by April of the following year, also yielding around 2,500 kg per mu. Lettuce should be planted early using fast-maturing varieties to ensure timely harvest.
For legumes, early broad beans are sown in October and harvested in April, while early peas can also be grown. The pea heads can be sold in morning markets, and green pods can be harvested the following year.
Forage crops like Rumex, alfalfa, and ryegrass are highly productive, often producing over 3,000 kg of fresh grass per mu.
During the summer "casual period," intercropping continues. Solanaceae crops such as tomatoes, eggplants, peppers, and potatoes are usually sown under plastic film before April and transplanted into mulberry fields in mid to late April. Cucurbitaceae crops like watermelons, melons, and gourds are also started in April with seedlings and transplanted into mulberry fields at the same time. Umbelliferae crops such as celery are first grown as strong seedlings before being transplanted.
In newly expanded mulberry gardens, intercropping during the "un-planted period" is possible. Summer intercropping options include oilseed crops like soybeans, peanuts, and sesame; solanaceae crops like tomatoes, eggplants, peppers, and potatoes; cucurbitaceae crops like watermelon, wax gourd, and melon; and cruciferous crops like Xiayang No. 4 Chinese cabbage. In winter, legumes such as early broad beans and peas, along with forage crops like alfalfa, ryegrass, and Rumex, are suitable for intercropping.
In young mulberry gardens, intercropping can take place throughout the year. However, it's important to prioritize the mulberry trees and avoid planting tall-stalked or vine crops that could negatively affect their growth. This ensures that both the intercrops and the mulberry trees thrive together without competition.
