Overwintering protection method for pistachio

Abstract

The invention relates to an overwintering protection method of pistachio, which includes the steps that a layer of coldness defense materials is placed on the cultivation soil of the pistachio sapling and a proper amount of cultivation soil is added on the coldness defense materials; the coldness defense materials are the products of mixed fermentation of crop straw powders and farmyard manure orboards made by further pressing the fermentation product. The overwintering protection method of pistachio provided by the invention can increase the temperature of the soil nearby the roots of the pistachio, reduce the depth of frozen soil and branch tipping rate and increase the overwintering survival rate of pistachio; the coldness defense material can be used as fertilizer in spring, thus saving one planting process, reducing the labor intensity and labor cost and having remarkable significance in the popularization of the pistachio in great area.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for overwintering protection of pistachio by using earth-building supplemented with heat-retaining materials to improve the overwintering survival rate. Background technique [0002] Pistachio (Pistacia vera L.) alias Hu Zhenzi, Uyghur called Pistan (transliteration of Iranian Pistan), commercial name "pistachio", is the deciduous small tree of the genus Pistacia (Pistacia L.) of Anacardiaceae. Arbor, spherical crown, oval or oval fruit, mainly cultivated in the United States, Iran, Turkey, Afghanistan, etc. It is one of the world's four major nuts (walnuts, almonds, hazelnuts, and pistachios), and is a special and precious fruit . [0003] The fruit of pistachio has high economic value and is sold well all over the world. In recent years, the expensive "American pistachio" that has spread all over the Chinese market is the fruit of the artificially sel...

Problems solved by technology

[0004] In recent years, although my country has built a number of pistachio plantations, the cultivation area, yield and nut quality are still unsatisfactory. At the same time, due to climate and other factors, pistachio has also experienced extensive freezing damage during the growth process. For example, Kashgar, which is located on the southern edge of the Tarim Basin, is known for its warm climate in Xinjiang, with the lowest temperature not exceeding -13°C. However, since the winter of 2006, Kashgar has not only encountered a cold winter that has not been encountered in nearly 30 years, but some cultivation areas have experienced a cold winter that has not been encountered in 70 years. In the cold winter, the extreme low temperature reached -24°C. In mid-March, there were consecutive days of low temperatures ranging from -1°C to -2.5°C. The low temperature causes the flower buds to freeze, and the bark of the trunk and main branches to crack, resulting in almost no harvest in some plantations

In some areas, due to the lack of targeted antifreeze measures, almost all the annual pistachio seedlings were frozen to death after overwintering, and 70-80% of the two-year-old pistachio seedlings also suffered from freezing damage.
