Embodiment 1

[0017] Present embodiment utilizes the large umbrella forest of Chinese pine to prevent and control the method for newly-built mountain apricot grove late frost flowers and frozen fruit to comprise the following steps:

[0018] Step 1, when planting apricot plants, avoid low-lying grounds to build gardens, plant seedlings in spring 3-4 months and plant apricot plants, the planting density of apricot plants is 110 strains / mu, and select 1-year-old apricot saplings for planting;

[0019] Step 2, when planting apricot plants, excavate Chinese pine planting holes staggeredly at the periphery of the apricot forest and in the open space of the apricot forest by (5-6) × (6-8) m, and plant holes in the rainy season of the same year 7-8 Chinese pine was planted in the Chinese pine planting hole in August, and the 5-year-old Chinese Chinese pine cup seedling was selected as the planted Chinese pine. The cultivation soil filled in the Chinese pine planting hole was a mixture of soil and 2...

Embodiment 2

[0030] The embodiment of the present invention utilizes the large umbrella forest of Pinus tabulaeformis to prevent and control the method of late frost flowers and frozen fruits applied to the perennial wild almond forest. The operating method comprises the following steps:

[0031] Step 1, at first remove diseased insect strain and senescent strain in the perennial wild almond forest, pruning the almond plant simultaneously, adjust the wild almond plant density to be 110 strains / mu.

[0032] Step 2, one year in advance for the perennial wild almond forest in autumn in the peripheries of the almond forest and in the open space of the almond forest by (5-6) * (6-8) m row spacing staggered excavation pinus tabulaeformis planting hole, The planting holes dug in advance can store water and keep moisture. When the next rainy season is July to August, Chinese pine will be planted in the Chinese pine planting holes to ensure that the Chinese pine plants are more than 50cm higher than...

Abstract

The invention provides a method for preventing and controlling flower freezing and fruit freezing of armeniaca sibirica due to late frost by a Chinese pine big umbrella forest. According to the method, Chinese pines are planted on the periphery of an armeniaca sibirica forest and in vacant spaces inside the forest; the height of the Chinese pines is more than 50cm higher than the height of the armeniaca sibirica; the planting row spacing of the Chinese pines is (5 to 6)*(6 to 8); the plant number ratio of the armeniaca sibirica to the Chinese pines is (6 to 8):1; and before the Chinese pines are planted, the planting density of the armeniaca sibirica is controlled to be 110 plants/mu. The method provided by the invention is used for a large-area armeniaca sibirica forest with possibility of suffering from late frost disasters; an umbrella-shaped protection forest formed by planting the Chinese pines can effectively decelerate the wind speed to achieve the effects of a plurality of small wind barriers, and can be used for effectively weakening cold air in winter, shading the burning sun in summer and shielding late frost and early frost in spring and autumn; the site conditions canbe improved; the seedling preserving rate, the fruiting rate and the yield can be improved; the natural environment can also be beautified; no any pollution and no safety hazard can be generated; andthe method conforms to an ecological civilization development mode.

Description

technical field [0001] The invention relates to a method for preventing and controlling late frost, flower and frozen fruit disasters of mountain apricot, in particular to a method for preventing and controlling late frost, flower and fruit of mountain apricot by using large umbrella forests of Chinese pine. Background technique [0002] Prunus apricot can not only beautify the green environment, but also increase farmers' income. It is a pioneer tree species and an economic tree species for afforestation in the semi-arid areas of northern my country. During the flowering period, apricots often encounter late frost hazards, which seriously affect the growth and fruiting of apricots, resulting in reduced production or even no harvest. The harm of apricot late frost is a worldwide problem. Researchers at home and abroad have carried out a large number of experimental studies and developed a variety of anti-frost methods and technologies with different ideas, but each of these ...
