- Abstract:
- Balanced sowing is the main factor affecting the cultivation of vegetables in tropical areas, especially in summer. Based on the following parameters associated with the balanced production of fast-growing leafy vegetables, harvest duration (A), growth duration (B), land fallowing duration (C), cultivation area (W), planting proportion of a specific vegetable (Y) and required sowing area (X), the balanced sowing mathematical formula X=(A/(B+C))×W×Y was derived. The effectiveness of this model was validated using four fast-growing leafy vegetables, water spinach (Ipomoea aquatica Forssk. ‘Fenghuang liuye’), flowering Chinese cabbage (Brassica campestris L. subsp. chinensis var. utilis ‘Sijiu youqingtian’), pak choi (B. campestris subsp. chinensis var. communis ‘Siji’) and Chinese leaf mustard (Brassica juncea var. multiceps ‘Xiye’), during the summer and fall seasons in Hainan province. The results show that the daily harvest yield of each tested vegetable was close to the average, making the daily harvest yield of each vegetable relatively stable.
