A Preliminary Report on the Experiment of Spraying Calcium Reduce Jujube Fruit Cracking in Laoling City
Abstract: Ziziphus jujuba is a high-quality dried jujube variety in our country, which is widely cultivated in its birthplace Laoling city of Shandong province, but the fruits’ main defect is that its peel is very thin and easy to crack. In Laoling city, LaoLing science and technology backyard had worked with local agriculture and forestry department in May 2014 to study the Ziziphus jujuba, the results show that in the normal year, the fruit is with a cracking rate of 30%, but in a rainy year the cracking rate is as high as 80%. Cracking has caused serious influence on fruit production and sales, how to prevent the fruit from cracking before harvest has become an urgent problem. We have tested the effect of foliar spray of calcium substances to prevent the fruit from cracking before harvest, aiming to propose some measures to induce the cracking of Ziziphus jujuba.
