Improvement of cultivation techniques

• Micro-spray techniques of passion fruit in 2020：the passion fruit 'Gypsophila' planted in Changhua is treated with micro-spray to increase the humidity in September and October, which can improve the problem of bud dropping caused by high temperature, help increase fruit setting and thereby increase the growth resistance.
• Construct the Good Agriculture Practices and the key technology of production management for exporting orchards of pitaya in 2019.
• Micro-spray technology of grape in 2019：micro-spray was developed to treat grape 'Kyoho' during the flowering stage, which has the effect of improving fruit setting.
