Embodiment 1

[0032] (1) Select the 5-year management trimming, the tree is basically consistent, and the tree has a lot of trees. In mid-August, the tree tray was 15cm, and in mid-November (watering to the watery of the soil layer 40 to 50 cm), the first year (the second year of soil was thawed until the flowering before the flowering) watered 1 time ( Every 10 days 1 time).

[0033] At the beginning of March of the following, the trunk was coated.

[0034] (2) After the soil is thawed (mid-March), with a apricot, the anti-cold antifreege gas is used, and 50L (fully impregnated into the root system) per tree.

[0035] (3) The second year of March, spraying plant growth regulator solution, spray once every 7 days, continuous spraying;

[0036] Plant growth regulator solution: ABA 50 mg / l, NaA 250mg / L, 20 mL polyethylene glycol (moisturizing agent), 0.15 g / L inositol (through-infiltration), 0.4 g / L polyvinyl alcohol (PVA17-88, Adhesive).

Embodiment 2

[0041] (1) Select the 5-year management trimming, the tree is basically consistent, and the tree has a lot of trees. In mid-August, the tree tray was covered with 20cm. In mid-November (water to the watery soil layer 40 to 50 cm), the second year (the second year was thawed until the soil was thawed until the flowers) water 2 times ( 1 time every 12 days).

[0042] At the beginning of March of the following, the trunk was coated.

[0043] (2) After the soil is thawed (mid-March) uses the apricot to resist the cold antifreege pot, each tree 80L (fully impregnated into the root system).

[0044] (3) The second year of March, spraying plant growth regulator solution, spray once every 7 days, continuous spraying;

[0045] Plant growth regulator solution: ABA 60 mg / l, NaA 280mg / L, 30 mL polyethylene glycol (moisturizing agent), 0.25 g / L inositol (acoustic agent), 0.5 g / L polyvinyl alcohol (PVA17-88, Adhesive).

Embodiment 3

[0050] (1) Select the 5-year management trimming, the tree is basically consistent, and the tree has a lot of trees. In mid-August, the tree tray is 25cm, and the water is watered once in early December (watering to the infiltrating soil layer 40 to 50 cm), the next year (the second year of soil is thawed until the soil until the flowers before flowering).

[0051] At the beginning of March of the following, the trunk was coated.

[0052] (2) After the soil is thawed (mid-March), with a apricot, the anti-cold anti-frozen agent, each tree 100L (fully impregnated).

[0053] (3) At the beginning of April, the plant growth regulator solution was sprayed, sprayed once every 7 days, continuous spraying;

[0054] Plant growth regulator solution: ABA 80 mg / L, NaA 350mg / l, 40ml polyethylene glycol (moisturizing agent), 0.3 g / L inositol (acoustic agent), 0.6 g / L polyvinyl alcohol (PVA17-88, Adhesive).

[0055] Spraying the apricot, the anti-frozen agent, the time according to the we...

Abstract

The invention discloses a method for improving cold resistance of kernel apricots in a flowering period and application of the method, and relates to the technical field of crop antifreeze agents and application thereof. The invention provides a cold-resistant anti-freezing agent for kernel apricots in the flowering period. Each liter of the cold-resistant anti-freezing agent comprises the following components: SA, sodium lactate, cane sugar and the balance of water. The invention also provides a cold-resistant method applying the cold-resistant anti-freezing agent. The method can obviously reduce the freezing injury rate of the kernel apricot flowers when night frost comes. Through a spraying mode of combining the growth regulator and the cold-resistant anti-freezing agent for the kernel apricots in the flowering period, the purposes of delaying the flowering period and improving the freezing resistance of the flowers are achieved, and a foundation is laid for improving the yield of the kernel apricots.

Description

Technical field [0001] The present invention relates to a crop antifreeze and its application techniques, and more particularly to a method of improving the anti-cold trolling during the regeneration. Background technique [0002] Prunus armenia × sibirica is a rose Kada plant, mainly including the production of the large densita and producing bitter almonds in the production of sweet almonds. It is an important economic forest tree in my country. It is an important wood grain and oil resources. The oil content is 63%. Renned anti-drought, cold resistance, thin resistance, wide adaptation, short cultivation cycle, high economic value, is the ideal tree species of mountain greening and increasing the income of mass, with good economic, social, ecological benefits. [0003] However, there is still a problem in production instability in the production of the ritcyry. The main reason is that the use of apricots in the spring, which is easy to be harmful to the night cream, leading to...
