Soilless Culture Techniques of Zizania latifolia

Soilless cultivation is an important technology in the planting industry. in the era of increasingly precious land resources and aggravating contradiction between human and land, soilless cultivation seems to be a new opportunity for the development of planting industry. The cultivation of Zizania caduciflora has always been a way of soil cultivation, allowing it to grow in the field.

Soilless cultivation techniques of Zizania caduciflora

1. First of all, we should buy water pipes of different thickness, design the shape according to the actual area of the site, punch holes in the pipe and connect it. And do a good job of the reflux system to ensure the smooth flow.

2. Put all the cultivated blue into the pipe hole, and put 2-3 vegetable seeds in each according to the plant, then germinate, keep the strong seedlings, and pull out the bad ones.

3. You can also use a seedling box to raise seedlings first, and when the seedlings grow to the point that there are 3 leaves of 2 murmurs, you can transplant them into the cultivated blue and continue to grow. Generally, seedlings can be transplanted in about 10 days.

4. The nutrient solution for vegetable planting is added through the water pipe and recycled, so that each vegetable can absorb the nutrition. The vegetables can grow rapidly and the harvest is in sight.

5. At this point, we have to ask how to make the nutrient solution of soilless cultivation. Now all the agrotechnical stations have to buy it. According to the ratio on the manual, the price is not high.

6. The water used is fine with tap water. It is best to put tap water for use for a few days, or it is good to collect Rain Water on rainy days, and it is best not to collect Rain Water in the first 20 minutes.

How much is the seed of Zizania caduciflora per jin

Zizania latifolia can not be propagated by seeds, but usually propagated by ramet method. The price of each plant is generally about 2-4 yuan, but the price varies greatly due to the variety, quality and producing area of the plant. The seed quality of Zizania caduciflora directly affects the rate, yield and quality of Zizania caduciflora, but the difference in time, quantity and cultivation management level of smut fungus often leads to species degradation and the emergence of male and grey Zizania latifolia, so the species should be strictly selected every year.

Environment of producing area of Zizania caduciflora

Zizania caduciflora is a temperature-loving plant, which can grow at a suitable temperature of 10-25 ℃ and is not tolerant to cold, high temperature and drought. The double-season Zizania latifolia is planted in the plain area, which requires less sunshine and higher water and fertilizer conditions, and temperature is an important factor affecting the pregnancy of Zizania latifolia.

Zizania caduciflora has developed root system and large water demand, which is suitable for clay loam or loam with sufficient water source, convenient irrigation, deep and soft soil, fertile soil, rich in organic matter and strong ability of water and fertilizer conservation.

Zizania caduciflora can be divided into two types: single-season Zizania latifolia in autumn and double-season Zizania latifolia in autumn and summer, all of which are propagated separately. Zizania latifolia in the Yangtze River basin is planted in Qingming to Grain Rain, in summer and autumn in spring and autumn, before and after Grain Rain in spring and before and after the Beginning of Autumn in autumn.

What are the varieties of Zizania caduciflora

1. Zhejiang Zizania latifolia No. 2: Zhejiang Zizania latifolia No. 2 is a double-season medium-ripe variety of Zizania caduciflora, which is short and chubby in shape, smooth, white, delicate in texture, non-fiber and delicious. The field has strong growth potential, green and firm leaves, strong stress resistance, wide adaptability, high quality and high yield.

2. Shuizhen No. 1: Zizania caduciflora No. 1 is a mid-late mature variety, which is suitable for spring planting and high temperature tolerance. The peak period of Zizania latifolia production in summer is from mid-June to mid-July, and the peak period in autumn is from mid-September to early October. It has wide adaptability, high yield and high quality, and the yield per mu is 1786.6 to 1986.7 kg.

3. Lijiao No. 1: Zizania caduciflora No. 1 has strong growth potential, compact plant type, large individual, white and smooth appearance, delicate meat, and a yield of 1500-2000 kg per mu, which is suitable for planting in alpine areas above 400 meters above sea level. the mature period is from late July to mid-August.

4. Hard-tailed Zizania caduciflora: the tender stem of hard-tailed Zizania caduciflora is spindle-shaped, 17 cm long, 6 cm in transverse diameter, with 3-4 nodes, and a single diamond weighs 15-20 grams. Heat-resistant and fertilizer-resistant, the meat is white and the part of Zizania latifolia is high. The quality is good, with a yield of 1250-1500 kg per mu and harvested in Guangzhou from September to November.

5. Wuxi Yan Zizania latifolia: Wuxi Yan Zizania latifolia has exuberant tillers, late maturity, enlarged bamboo shoots, the best quality, high yield, many verrucous wrinkles on the surface of the stem, white color, 750 kilograms per mu in autumn and 1500 kilograms in summer.

The development of Zizania caduciflora soilless cultivation technology will bring a new development opportunity to the cultivation of Zizania caduciflora. On the one hand, it saves the cost of land, on the other hand, it makes a great contribution to the cause of environmental protection. Of course, the soilless cultivation of Zizania latifolia should also follow the growth law of Zizania caduciflora.
