Matters needing attention for the latest cultivation of Zizania caduciflora in greenhouse

Zizania caduciflora is a kind of aquatic vegetable, so it is generally cultivated in the south, but with the development of agricultural technology, it is not only cultivated in the south where there is plenty of water, but also can be cultivated all over the country. And through the greenhouse technology can also accelerate the growth of Zizania caduciflora, but also pay attention to some problems, let's take a look at it with the editor.

1. Fertilizer and water management

On the basis of sufficient base fertilizer and seedling stage, strong stalk fertilizer should be applied in time after the seedlings are fixed in early April, which is beneficial to the stout stem, generally applying 30 kg imported compound fertilizer per mu. When 1/3 of the plants begin to get pregnant, the leaves are still relatively young, and 20-30 kg of compound fertilizer can be applied per mu to ensure the nutrition needed in the future. From March to April, the management is mainly furrow irrigation, to establish a good irrigation water layer, after pregnancy, the water layer will be deepened to 15 cm, in order to improve the quality of Zizania latifolia.

2. Prevention of drug damage and fertilizer damage

In the process of cultivation in the greenhouse, the most important thing is to prevent drug damage and fertilizer damage, so the use of hydrocarbon, urea and other volatile fertilizers and any chemical herbicides are not allowed in the greenhouse. Only an appropriate amount of ternary compound fertilizer is used to prevent the burning of chemical fertilizers and herbicides. In addition, after fertilization, attention should be paid to ventilation in order to discharge the gas emitted from the fertilizer during decomposition and promote the better growth of Zizania caduciflora.

3. Prevent high temperature burns

In March, greenhouse ventilation is extremely important, should often open both ends of the door membrane for ventilation during the day, and should be sealed and insulated at night. When the daytime temperature reaches 18 degrees and the temperature in the greenhouse reaches about 32 degrees, the film at both ends of the greenhouse should be opened in time for ventilation, which is beneficial to the growth, development and health of seedlings. When the daytime temperature reaches more than 20 degrees, it is necessary to remove some or all of the greenhouse film in time, and it is appropriate to control the indoor temperature no more than 30 degrees, so as to prevent the seedlings from being burned by high temperature.

4. Anti-freezing

In early spring, the temperature changes sharply, there are two films on both sides of the greenhouse, and the skirt edges on both sides have to be adjusted. When the temperature is stable in April, all the films can be removed, but if the film is removed prematurely, Zizania caduciflora will be damaged by cold air and the harvest time will be delayed, so we must pay attention to it.

The above is the greenhouse cultivation of Zizania caduciflora points for attention, hope to help you, want to know more related knowledge, please follow us.
