Rapid seedling cultivation method of Prunus pedunculata Maxim.

Abstract

The invention discloses a fast seedling method of longstalck peaches, comprising: selecting ground temperature stably more than 10 DEG C in spring, seeding 20-25 kg seeds of longstalck peaches per mou; preparing the seeds of longstalck peaches one month ahead of time, placing the seeds of longstalck peaches in a container, burning the seeds using boiled water, meanwhile adding boiled water and mixing, wherein the quantity of the boiled water is added till immersing the seeds, and water temperature is mixed till the water does not burns hands, later on changing clean water once a day for seven days; mixing and accumulating the soaked seeds of longstalck peaches with the sand in a ratio of 1:3, covering with a plastic film for accelerating the germination of seeds, checking the seeds after seven days, seeding when the seeds shoot up, wherein row pitch in seeding is 30 cm, and plant spacing is 2cm to 4 cm. Routine field management is performed after seeding, complementary fertilizer is performed for two times in the middle period, the seeds come out when coming to the standards. The inventive method saves precious germplasm resource and sand storing cost in winter, nursery seedling date is high, which lays a good foundation for comeback of longstalck peaches and utilization of biomass energy.

Description

technical field [0001] The invention relates to the technical field of seedling-raising of cold-resistant economic plants in sandy areas, and further relates to a rapid seedling-raising method of long-stalked almonds. Background technique [0002] Long handle almond, has another name called handle almond, wild cherry (Amygdalus pcdunculata Pall.) is a plant of the subgenus Amygdalus (Amygdalus) of the family Rosaceae. It is a unique wild species of almond in my country. It used to be a shrub plant widely distributed in the sandy land of northern Shaanxi and Inner Mongolia. It has a strong desert survival ability and sand-fixing effect, and the seed kernel is rich in oil, protein and various minerals; but Due to desert inundation and human destruction, the distribution is scattered and extinct. The 1992 edition of "Atlas of Rare and Endangered Plants in Inner Mongolia" listed almonds as a second-class endangered plant. In 2002, published by the Forestry Department of Shaanxi...

), but it is difficult to be accepted by producers to remove a large number of seed husks when raising a large number of seedlings

[0005] The traditional sand storage seedlings need to soak the seeds in winter, and mix the sand with the long-stalked almond seeds in a certain proportion. Because the temperature in the sandy area rises quickly and unstable in spring, often the long-stalked almond seeds germinate and encounter low temperature. , Fusarium wilt often occurs at low temperature, resulting in dead seedlings, affecting the rate of seedling emergence; if the seeds are not sown in time, the seed buds will be too long, the buds will be broken during sowing, and the seeds will be lost. These are very difficult problems encountered by farmers in production. The problem
