Problems solved by technology

But this method is difficult to excavate, the amount of labor is large, the cost is high, and the multiplication coefficient is low, generally 8-10 times; the second is before and after the beginning of summer, when the dormant ramet buds of overwintering grow to 60-90 times. Centimeters, uprooted from the base of ramets, cut off the upper part of the leaves, and then planted with single injection
But it must be carried out at the right time, small seedlings are not easy to survive, and large seedlings are not easy to pull out; third, in the rainy season, the plants are cut from the moss tube in the water and planted as wild rice seedlings, but the survival rate is low, generally 30%. -40%

Embodiment 1

[0022] The rapid multiplication method of Zizania japonica of the present invention, the method is carried out according to the following steps:

[0023] 1) Selection and pretreatment of propagation site: Select the shallow water area of ​​a flat lake area that can irrigate and drain 10-50 cm deep water as the seedbed, and spread plastic sheets on the bottom of the seedbed to prevent the roots of the wild rice grass from being unrestricted. Late emergence caused difficulties.

[0024] 2) Preparation and laying of nutrient soil for seedbeds: use high-quality humus as organic matter and mix it with pond mud at a ratio of 3.5:1.5, and add 0.1% of the total amount of substrate DAP. This ratio makes the substrate light and easy to grow. The seedlings are transported, the root system is protected, and it is beneficial to the growth of the seedlings at the seedling stage. Spread the well-mixed nutrient soil on the plastic sheet or plastic film with a thickness of 10 cm, and pour 10 ...

Embodiment 2

[0031] The rapid multiplication method of Zizania japonica of the present invention, the method is carried out according to the following steps:

[0032] 1) Selection and pretreatment of propagation site: Select a flat abandoned pond capable of irrigating and draining 10-50 cm deep water as the seedbed, and spread plastic film on the bottom of the seedbed to prevent the root system of wild rice weed from unrestricted rooting, causing Late emergence caused difficulties.

[0033] 2) Preparation and laying of nutrient soil for seedbeds: mix grass-carbon soil with pond mud at a ratio of 4.5:0.5, and add 0.3% potassium dihydrogen phosphate to the total amount of the substrate. This ratio makes the substrate light and It is convenient for the transportation of the seedlings, protects the root system, and is beneficial to the growth of the seedlings at the seedling stage. Spread the well-mixed nutrient soil on the plastic sheet or plastic film with a thickness of 15 cm, and pour 20 ...

Embodiment 3

[0040] The rapid multiplication method of Zizania japonica of the present invention, the method is carried out according to the following steps:

[0041] 1) Selection and pretreatment of propagation sites: Select a flat coal mine subsidence land that can irrigate and drain 10-50 cm deep water as the seedbed, and spread plastic sheets on the bottom of the seedbed to prevent the roots of wild rice weeds from entrapping unrestrictedly, causing Late emergence caused difficulties.

[0042] 2) Preparation and laying of nutrient soil for seedbeds: Mix rotten leaf soil with pond mud at a ratio of 4:1, and add 0.2% of the total amount of substrate. This ratio makes the substrate light and It is convenient for the transportation of the seedlings, protects the root system, and is beneficial to the growth of the seedlings at the seedling stage. Spread the well-mixed nutrient soil on the plastic cloth or plastic film with a thickness of 12 cm, and pour water for 15 cm to wait for sowing.

Abstract

The invention provides a rapid Zizania latifolia propagation method, belonging to the technical field of Zizania latifolia cultivation. The method comprises the following steps of: 1) selecting and pre-treating a propagation field; 2) preparing and laying seedbed nutrient soil; 3) selecting seedlings; 4) planting the seedlings; 5) the management of water level at a seedling stage; 6) the management at a wintering period; and 7) lifting up the seedlings from the seedbed. Compared with the method of directly digging tiller seedlings, plant division seedlings or moss tubes from lakes in the existing conventional agricultural production, the rapid Zizania latifolia propagation method provided by the invention has the advantages of rapid propagation speed, high propagation coefficient which isgenerally 35 times to 40 times, easiness in planting, high survival rate, high seedling output, easiness in cultivation, time saving, labor saving, low seedling raising cost and the like. Moreover, the cultivated seedlings have the advantages of full stand through one-step planting, uniform and strong seedlings and the like, and the rapid popularization and planting in fields are facilitated moregreatly.

Description

(1) Technical field [0001] The invention relates to a cultivation technology of wild wild rice shoots, in particular to a rapid multiplication method of wild wild wild rice shoots. (2) Background technology [0002] There are more than ten species of aquatic economic plants in Nansi Lake. Among them, Zizizania japonica has a growing area of ​​5,000 mu, the largest area in history is 100,000 mu, and the promotion area is 200,000 mu. Zizizania japonica has a wide range of uses and is a high-quality feed with broad production prospects. Traditional breeding and planting methods: First, before and after Grain Rain, when a large number of dormant buds germinate on the mother plant, and most of the seedlings reach 30-40 cm in height, use a large shovel to insert from under the soil, dig out the mother plant pier, and place the mother pier along the ground. The growth of tillers is divided into several small piers, and each pier has 2-3 new seedlings with a height of more than 30 c...
