Embodiment 1

[0049] 1. Seedling selection and cultivation

[0050] 1.1 Selection of seedling land: In April 2010, 2 mu of nursery land in Minqin Psammophyte Botanical Garden was selected, and the soil was sandy loam;

[0051] 1.2 Cultivation in the nursery: After selecting the nursery, deep plow once on October 20, 2010, at a depth of 20cm, and then expose to the sun. On December 17, enough winter water was poured to survive the winter. Shallow plowing was carried out on March 26, 2011, with a depth of 15cm; combined with shallow plowing, the base fertilizer was 1800kg each of decomposed cow and sheep manure, and 35kg of urea; then rake, harrow and suppress to level the ground and remove grass roots and stones with other sundries.

[0052] 2. Seedbed making

[0053] 2.1 Soil preparation: On the well-cultivated nursery land, finely prepare the land, remove grass roots and stones and other debris, level the land, and apply 2000kg of poisonous soil into the soil while preparing the land. ...

[0089] 1. Seedling selection and cultivation

[0090] 1.1 Selection of seedling land: In April 2011, 1 mu of sandy spruce nursery land in Gansu Minqin Comprehensive Sand Control Experimental Station was selected, and the soil was sandy loam;

[0091]1.2 Nursery cultivation: On October 22, 2011, the nursery was deeply plowed once to a depth of 15cm, and then exposed to the sun. On December 21, enough winter water was poured to survive the winter. On March 26, 2012, shallow plowing was carried out with a depth of 15 cm; in combination with shallow plowing, basal fertilizer was applied, and the basal fertilizer was 800 kg each of decomposed cow and sheep manure, and 17 kg of urea; the rest were the same as in Example 1.

[0092] 2. Seedbed making

[0093] 2.1 Soil preparation: according to the weight ratio of phoxim:sand is 300kg:900kg, poisonous soil is configured, and a total of 1200kg of poisonous soil is applied to the soil, and the rest are the same as in Example 1;

[0129] 1. Seedling selection and cultivation

[0130] 1.1 Selection of seedling land: In April 2012, 0.5 mu of nursery land at Jinta County Sand Control Station was selected, and the soil was sandy loam;

[0131] 1.2 Cultivation in the nursery: After selecting the nursery, plow once on October 22, 2012, at a depth of 25cm, and then expose to the sun. On December 24, enough winter water was poured to survive the winter. On March 22, 2013, shallow plowing was carried out, with a depth of 20cm; in combination with shallow plowing, basal manure was applied, and the basal manure was 600kg of decomposed cow dung, 800kg of sheep manure, and 4kg of phosphorus diamine; all the other were the same as in Example 1;

[0132] 2. Seedbed making

[0133] 2.1 Soil preparation: shallow plowing was carried out on April 5, and 600kg of poisonous soil for preventing underground pests was applied to the soil to level the ground; the weight ratio of poisonous soil was phoxim: sand = 150kg: 450kg;...

Abstract

The invention relates to the technical field of fine tree species seed seedling raising, in particular to a field seed seedling raising method for picea mongolica in an arid desert area. The method includes the steps of seedling field selecting and farming, seedbed manufacturing and disinfecting, seed processing, sowing, field management in the seedling stage and seedling overwintering management. The problem that in the prior art, research experiments on picea mongolica stay in seedling raising in a greenhouse or a nutrition bowl is solved, the seedling raising method which is low in cost, complete and comprehensive in system, good in seedling raising effect and high in practicability is provided for greatly cultivating fine tree species picea mongolica for wind prevention and sand fixation in the arid desert area, the existent seedling ratio of nursery stock reaches 82-88.4%, an effective and feasible guarantee is provided for constructing protection forest for the arid desert area and used for ecological environment construction better, and an effective method is provided for nursery stock breeding of picea mongolica in the arid desert area.

Description

technical field [0001] The invention relates to the technical field of seedling raising of excellent tree species, in particular to a seedling raising method of spruce field seeds of excellent tree species for windbreak and sand fixation in desert areas. Background technique [0002] Sand Spruce ( Picea mongolica ) is an evergreen tree belonging to the Pinaceae Picea genus. It is a rare and precious tree species in the world, and it is also a unique tree species in my country. Natural forests are only distributed in the Inner Mongolia Autonomous Region, and are concentrated in Hexigten Banner. Sandy spruce natural forests are distributed in a small area and natural regeneration is difficult, resulting in a reduction in the number of natural forests. Sandy spruce will soon become a rare and endangered plant in my country. Sand spruce has grown on dry and barren sandy land for a long time, forming many characteristics of adapting to drought, cold and barrenness. In addition...
