In 2020, a late spring cold snap struck—Nongda products are here to help you weather the challenge.

Due to the pandemic, humanity’s start to 2020 was extremely difficult, and crops fared no better.

According to the forecast from the National Meteorological Center: From April 22 to 25, strong winds of force 4 to 6, with gusts of 7 to 9, are expected across North China, Northeast China, and eastern Huanghuai. The frost line will remain for two consecutive days across Ningxia, northern Shaanxi, most of Shanxi, and northern Hebei, leading to light to moderate frost damage in apple-growing areas and adversely affecting apples during the flowering‑fruit‑setting stage. In addition, this weather pattern will negatively impact other local economic fruit trees, open-field vegetables, greenhouse facilities, and livestock farming. The 5°C isotherm will extend through Guanzhong in Shaanxi, Shanxi, western and northern Henan, Hebei, and most of Shandong; these low temperatures will somewhat hinder the booting, heading, and flowering stages of winter wheat, particularly in fields with rapid growth but weak vigor or poor soil moisture, potentially compromising grain set in the later growth phase.

Since March, regions across the country have endured at least three bouts of late-spring cold snaps, leaving crops severely damaged and incurring heavy losses.

During this period, wheat was in the heading and flowering stage, and fruit trees were in bloom and undergoing pollination. This sudden drop in temperature has persisted for nearly a week, leaving bees too chilled to forage, so orchardists have been forced to resort to hand pollination. The recent frost and low temperatures have severely stressed cherry and apple blossoms; although many flowers have opened, seasoned farmers predict reduced yields for both apples and cherries this year. With spring alternating between two warm days and two cold ones, conditions have proven far from ideal for crop growth.

Regarding late spring cold snaps, farmers can implement appropriate remedial measures:

First and foremost, irrigate at the right time. Timely irrigation is a crucial measure for both preventing and mitigating frost damage, with a direct and pronounced effect on spring late‑frost injuries. Employ a variety of methods to expand the area under effective irrigation, ensuring that water is applied thoroughly and in sufficient quantity to guarantee quality and promote the resumption of growth.

For fruit trees, first, remove any remaining frost‑damaged flowers and young fruits. After freezing, the interiors of flowers and developing fruit turn brown; these should be promptly picked off to minimize nutrient consumption by the tree. Second, ensure effective pollination. To mitigate yield losses caused by frost during bloom and to encourage fruit set from marginal and axillary flowers, carry out thorough pollination throughout the orchard, regardless of the extent of frost damage. Additionally, smoke fumigation can be used to ward off cold and reduce frost injury.

For greenhouse vegetables, it is important to raise the temperature gradually rather than abruptly, to prevent frost damage and tissue necrosis caused by a sudden temperature spike. Second, manually spray water to increase air humidity inside the greenhouse, stabilize the internal temperature, reduce water loss from frost‑damaged tissues, and promote water uptake. Third, promptly remove frost‑damaged stems, leaves, and fruits to prevent mold and decay, which could lead to disease.

In response to this year’s extreme weather, experts at the Agricultural University have specially developed two high-tech foliar fertilizers—Ye Dong Li and Bao Jia Wei Guo—that enhance frost resistance and stress tolerance, helping farmers mitigate yield losses and minimize economic damage caused by late spring cold snaps.
