Application of regulators to improve watermelon fruit setting rate and yield
Chlorpyrifos
On the day when the female flowers of watermelon bloomed or 1 day before flowering, a 10 mg/L aqueous solution of chlorfenapyr was dipped with a writing brush to evenly coat the surface of the ovary and the stalk of the female flowers. It can significantly improve the watermelon fruit setting rate and reduce the fruit setting node position. The test showed that the fruit setting rate of female flowers treated with chlorfenuron was as high as 92.3%, the fruit setting index per plant was 1.8, and the fruit setting node position was 19.6, while the fruit setting rate of female flowers in the control was only 29%, the fruit setting index per plant was 0.6, and the fruit setting node position was only 29%. is 24.3.
6-BA
Applying 100mg/L benzylaminopurine to the stalk on the day of flowering can achieve the effect of promoting fruit set.
Gibberellic acid
Spraying 20～50mg/L gibberellic acid liquid once in flowering period or once in young melon stage can promote the growth and yield of young melon.
Zeatin
Spraying with 0.0015mg/L liquid medicine in the flowering stage, spraying once every 10d, spraying 3 times in total, can make the watermelon vines strong in the early stage, not fading in the middle and late stages, reduce the diseases such as blight and anthracnose, and reduce the sugar content in the later stage. and increased production.
Brassinolide
Spray with 0.02～0.04mg/L brassinolide solution at the young fruit stage and fruit expansion stage
Once, it can accelerate fruit growth and increase yield.
DCPTA
Spray 20-30mg/L DCPTA liquid evenly on the whole plant at the early flowering stage, after fruit setting, and fruit expansion stage, which can achieve good taste and juiciness, increase sugar content, increase the weight of single melon, early harvest, increase yield, and stress resistance. Good results.
Triacontanol
Spraying 0.5mg/L triacontanol and 0.2% potassium dihydrogen phosphate mixture once each when 5 true leaves, female flowers are in full bloom and about 250 g of young fruit has a significant effect on watermelon yield increase, which is 52.3%.
