Embodiment 1

[0058] Dongying Guangbei Farm No. 2 Forage Test Base, with a test area of ​​1335m2 2 The basic soil fertility of the test site is shown in Table 3, and the cutting test was started in mid-July, 2008.

[0059] Table 3 Soil fertility of each test base

[0060]

[0061]

[0062] Specific steps are as follows:

[0063] a. Seedbed preparation

[0064] On the land where Apocynum is going to be planted, select 10×10m 2 The land is used as a seedbed, mixed with crushed wheat straw and farmyard manure, plowed 20cm deep, raked and raked finely, and the surrounding area is used as a furrow, according to 4500m 3 / hm 2 The amount of irrigation is flooded with water to suppress the alkali. 150kg of farmyard manure and 100kg of crushed wheat straw were mixed with the soil and applied. Ridge by 1m ridge distance, ridge height 15cm, dig three rows of ditches in the ditch, ditch depth 15cm, width 20cm, the soil from the ditch is temporarily placed on the edge of the ditch, in order ...

Embodiment 2

[0078] The nursery base of Dongying City Garden Bureau is located in the northeast of Dongying City, with a test area of ​​800m 2 The basic soil fertility of the test site is shown in Table 4, and the cutting test was started in August 2008.

[0079] Specific steps are as follows:

[0080] a. Seedbed preparation

[0081] Select 5×10m on the land to be planted with apocynum 2 The plot serves as a seedbed. Add 50kg of sand, 75kg of farmyard manure, plow 20cm deep, rake level and rake finely, make furrows around, according to 5000m 3 / hm 2 According to the ridge spacing of 1m, the ridge height is 20cm, and three rows of furrows are dug in each furrow, the depth of the furrow is 15cm, and the width is 20cm. Bury cutting seedlings.

[0082] b. Stem segment selection

[0083] In mid-August, select thick branches with a diameter greater than 0.4 cm at the base, and cut cuttings with a length of 20 cm. When sampling, on the same plant, the cuttings are selected from the middle...

Embodiment 3

[0095] Linzi Village, Qingtuo Town, Kenli County is adjacent to the Yellow River in the west, with a test site area of ​​1800m 2 , sufficient irrigation conditions, but serious soil salinization. The basic soil fertility of the test site is shown in Table 4, and the cutting test was started in August 2009.

[0096] Specific steps are as follows:

[0097] a. Seedbed preparation

[0098] Select 10×12m on the land ready to plant Apocynum 2 The plot serves as a seedbed. Add 150kg of farmyard manure, plow 20cm deep, rake level and rake finely, make furrows around, according to 4800m 3 / hm 2 The amount of irrigation is flooded with water to suppress the alkali. Ridge according to 1m ridge distance, ridge height 20cm, dig three rows of ditches in each furrow, ditch depth 15cm, width 20cm, the soil from the ditch is temporarily placed on the edge of the ditch to prepare for filling the cutting seedlings.

[0099] b. Stem segment selection

[0100] In early August, select thick...

Abstract

The invention relates to a method of utilizing stem section cuttage to reproduce apocynum venetum in alkali soil. Obtained apocynum venetum cuttage seedlings are directly used for plantation in the alkali soil. The method comprises the steps of seedbed preparation, stem section selection, stem section processing, cuttage, seedbed management, land preparation, field transplantation, field management and the like. Field planting experiments are performed in the area of the Yellow River Delta by means of the method, the cuttage survival rate is over 80%, and the method has wide application prospects. The method of utilizing the stem section cuttage to reproduce apocynum venetum in the alkali soil is an alkali soil efficient-utilization technology which is simple and convenient to operate, does not damage wild environments of apocynum venetum and can achieve quick plantation.

Description

technical field [0001] The invention relates to a method for propagating apocynum apocynum, in particular to a method for propagating apocynum apocynum by stem cuttings on saline-alkali land, and belongs to the technical field of ecological agriculture. Background technique [0002] The Yellow River Delta is located along the coast of the mouth of the Yellow River in the southern part of the Bohai Sea. It has unique land resources, with nearly 8 million mu of unused land, including 2.7 million mu of saline-alkali land. The unique ecological environment in this area has bred a large number of wild and precious germplasm resources, and Apocynum is one of them. In recent years, as the high-efficiency ecological economic zone in the Yellow River Delta has risen to a national strategy, and energy plants and medicinal plants have gradually been valued, apocynum resources have become a hot spot in the development of this zone. The current raw materials of apocynum products come fr...
