Effect test

Embodiment 1

[0041] Seedling cultivation was carried out in Hatu Tolgai Gacha, Jilantai Town, Alxa Left Banner.

[0042] a) nursery ground

[0043] The environmental conditions of the nursery ground are sandy loam plots with leeward sun, convenient water source, relatively flat terrain, and soil salt content less than 1%.

[0044] b) land preparation

[0045]Carry out soil preparation and soil disinfection in spring, and plow the soil to a depth of 20 cm to remove debris such as grass roots.

[0046] c) Seed and soil treatment

[0047] Before sowing, use 50% wettable carbendazim powder, 1 kg per mu, to sterilize the soil on the seedling ground. Before sowing, use 0.3% potassium permanganate solution to rinse the seeds once, soak the seeds for no more than 1 minute, and dry them in the sun after disinfection.

[0048] d) Seeding and drip irrigation belt layout

[0049] Sowing time is mid-April. Use the second-level seeds of "DB15 / T281 Main Afforestation Seed Quality Classification in ...

Embodiment 2

[0057] The difference between this embodiment and embodiment 1 is that in step b), the plowing depth of the soil preparation is 24 cm.

Embodiment 3

[0059] The difference between this embodiment and embodiment 1 is only that: in step d), the parallel row distance is 24 cm, and the sowing width is 14 cm.

Abstract

The invention provides a mechanical sowing, drip irrigation and seedling raising method for haloxylon ammodendron, and belongs to the technical field of xerophyte cultivation. According to the method, a seeder comprising a seeder and a soil covering box is selected for drilling and sand covering, drip irrigation belts are laid between rows, and the water yield of the drip irrigation belts per meter per hour is 2.4-2.5 kg. Through mechanical seeding, the consistency and precision of seeding and soil covering are improved, and the mechanization degree is greatly improved. Water and fertilizer management is conducted through the drip irrigation tape, irrigation is more uniform, the water resource utilization rate is higher, the method is not limited by the terrain, and the requirement for the land flatness degree is lowered. According to the method, the sowing time is saved, the labor efficiency is improved, the quality of the obtained haloxylon ammodendron seedlings is better, the seedling rate is higher, and the method is suitable for all areas capable of supporting arrangement of drip irrigation belts.

Description

technical field [0001] The invention relates to the technical field of xerophyte cultivation, in particular to a method for cultivating seedlings by means of mechanical sowing and drip irrigation by Haloxylon. Background technique [0002] Haloxylon (scientific name: Haloxylon ammodendron (C.A.Mey.) Bunge) is a Haloxylon ammodendron (C.A.Mey.) Bunge) is a Chenopodiaceae Haloxylon plant, a small tree, with a fleshy cortex that can perform photosynthesis, a well-developed root system, drought resistance, high temperature resistance, salt and alkali resistance, and wind erosion resistance , cold resistance and many other characteristics. Haloxylon natural forests are mainly distributed in northwestern Ningxia, western Gansu, northern Qinghai, Xinjiang, and Inner Mongolia; they are also distributed in Central Asia and Siberia, Russia. It grows on sand dunes, saline-alkali deserts, sandy lands by rivers, etc. Large areas of pure forest can be formed in desert areas, which can f...
