Loquat fruit antifreeze ability improving method

Abstract

The invention relates to the agriculture application field, and specifically relates to a loquat fruit antifreeze ability improving method comprising the following steps: using steel frames or bamboo timber to build a flat shed in an orchard before the cold wave in the last ten days of December every year, the flat shed is required to be 0.5m higher than the tree height, and the frame is firm; covering a shield net on the surface of the shed; uniformly spraying plant antifreeze water solution on the whole tree for 2-3 time in every 10 days in a period from the last 10 days of December to the early and middle parts of January every year, wherein the plant antifreeze solution is attenuated 500 times, and the attenuation ratio is volume ratio; after antifreeze spraying in middle January every year, removing tops and lower branches for opened inflorescence, only 2-3 branches in the middle are kept and sleeved with bags, so the inflorescence can open in middle of the bags without making contact with the bag wall. The method is suitable for open field and facilities, can improve loquat fruit antifreeze ability, thus reducing production loss.

Description

technical field [0001] The invention relates to the field of agricultural applications, in particular to a method for improving the antifreeze ability of loquat fruit. Background technique [0002] Loquat is a characteristic fruit native to our country. Because it is listed in early summer when there is a lack of fruit, it has a unique flavor and rich nutrition. It is deeply loved by the general public and has high economic benefits. Therefore, loquat has developed rapidly in my country in recent years, increasing from more than 140,000 mu in 1988 to more than 2.1 million mu in 2009, with an annual output of 1 million tons, accounting for more than 85% of the world's total, and an annual output value of 10 billion yuan. In 2015, the unit price of Suzhou Baisha loquat was 40-80 yuan / kg, and the unit price of high-quality large-fruit variety Guanyu was more than 80 yuan / kg. The economic benefits are very significant. [0003] However, loquat is an evergreen fruit tree that bl...
