2019年气象条件对中宁枸杞生长的影响分析

The analysis of the relevance between weather conditions and the growth of wolfberry in Zhongning Ningxia in 2019

2019年,宁夏气象条件对枸杞生产有一定的影响。其中,中宁枸杞主产区3—4月气温偏高,降水除4月下旬偏多外,其余时段均偏少,日照充足,有利于枸杞前期萌芽、展叶及春梢生长。5月气温偏低,日照持续偏少,对老眼枝开花及果实形成极为不利,且影响枸杞春梢生长、现蕾和开花。6月份多阴雨寡照天气且伴随低温,尤其是6月中旬—7月上旬4次大范围降雨过程,造成枸杞成熟、采收、制干受阻。多次降水过程导致枸杞花蕾脱落;加重了个别枸杞基地炭疽病等喜湿病虫害的发生蔓延;造成枸杞裂果、烂果、黑果,使枸杞产量和品质受到较大影响。

In 2019,the meteorological conditions in Ningxia have a certain influence on the production of wolfberry.Among them,the main production area of Zhongning wolfberry has encountered high temperature from March to April,and relatively low precipitation in late April,but the remaining time of the period is short and the sunshine is sufficient,which is conducive to early budding,leaf development and spring shoot growth of wolfberries.In May,the temperature is relatively low and the sunshine continues to be scarce,which is extremely unfavorable to the flowering and fruit formation of old eye branches,and affects the growth,budding and flowering of the spring shoots of wolfberries.In June,the weather was cloudy and rainy and was followed by low temperature,especially the 4 large-scale rainfall process from mid-June to early July,which hindered the maturation,harvesting and drying of wolfberries.The repeated precipitation process caused the flower buds of wolfberry to fall off;which aggravated the occurrence and spread of anthracnose and other wet-loving diseases and insect pests in some wolfberry bases;causing the fruit-cracking,the rotten and black fruits,which greatly affected the yield and the quality of wolfberries.
