There is such a vegetable that looks like garlic. Many people have never seen it, but people who have eaten feel delicious. It is a hoe. This vegetable cultivation is available in many areas, but since it is not a common vegetable on the market, some people have never seen it. Let's take a look at its planting techniques.
The head of è— (jià o ) is a perennial herb of the genus Liliaceae. It is cultivated in two years and can form small bulbs. It has a delicious taste and high medicinal value. It has the functions of digestion, degreasing, anti-cancer, etc. It is a veritable health food. . Shantou is generally planted in autumn, and is planted in Jiangxi, Fujian, Zhejiang, Hubei, Hunan, Sichuan, Yunnan, Guizhou, Guangdong, Guangxi and other provinces.
Taro cultivation techniques
1. Soil selection
It is advisable to plant sandy loam with high topography and good drainage performance, as well as clay and loam. In addition to the low field is not suitable, there are plain or hilly, hillside micro-acid to neutral soil can be planted, with a sandy soil of pH 6.2-7.0 planting better. Since the root system of taro can secrete propylene-based sulfides, it has an inhibitory effect on soil microorganisms. Therefore, it is not suitable for continuous cropping, and it is not suitable for connection with other onion and garlic vegetables. It is best to rotate with soybeans, peanuts, melons or rapeseed.
2, soil preparation
Before the crop is harvested, the ploughing is carried out after the harvesting. After the base fertilizer is applied, the stalking is suitable for the north-south direction. The width of the sorghum is about 2m, the width of the sulcus is 40cm and the depth is 17-23cm, depending on the terrain. If you use paddy fields to change to dry land, the ditch should be more than 20cm deep, and you need to make a "three ditch" package to ensure smooth drainage and dry rain.
3, reasonable close planting
Generally, from late August to mid-September, the local weather turns cold, and the average temperature drops below 25 °C. Select the plants with uniform bulb size, separate the bulbs one by one, and then select the seedlings with a diameter of more than 1.5cm, and cut the yellow leaves and the roots to grow.
Before planting, firstly, the row spacing is 18-20cm, and the shallow groove is 8-10 cm. Place the seedlings at a distance of 9-10 cm along the side of the ditch, so that the diameter ends face in the same direction, then open the first In the two trenches, the fine soil from the second trench is covered on the former ditch, so that the front ditch is flattened, and the seedlings are all buried in the soil, and about 30,000 plants/mu are planted. The thickness of the covering soil is preferably 6-8 cm. If it is too shallow, the bulb will be blue, and if it is too deep, the bulb will not be easily inflated. Moreover, the semi-horizontal planting can make a curved neck appear between the bulb and the ground in the future, which can prevent the rainwater from being washed out in the future, so that the stems are exposed to the soil surface, and the bulbs of the new tillers can be expanded in the soil to prevent See the light blue.
4, water and fertilizer management
The fertilizer requirement of steamed bread is that it is sulphur and not resistant to nitrogen. The ratio of pure nitrogen, phosphorus and potassium required during the growth period is 1:0.12:0.39, and high organic matter, humic acid and various medium and trace elements are required. Generally, the base fertilizer is fully fermented compost or manure 1.5-2 tons/mu, plus 40 kg/mu of superphosphate and potassium sulfate, and potassium fertilizer can be replaced by grass ash 300-400 kg/mu.
After the seedlings are released, the soil is loosened, topdressed, and shallowly removed to remove weeds. Topdress 10% decomposed thin manure water or 0.5% urea thinner water, the dosage is 1.5-2 tons / mu.
After the spring, use urea 20-60 kg / mu, potassium sulphate 20 kg / mu, divided into two times after the dew is dry and applied. In the late stage of bulb expansion, the planting line should be cultivated to prevent the bulbs from appearing green and old. During the growth period, especially in the spring, it is necessary to pay attention to drought prevention and drainage to prevent root rot and so on.
5. Pest control
The main pests of the taro are the onion thrips and the fly larvae mantle. The onion horse is very small, and both adults and larvae can forage the leaves, forming many fine long-shaped gray spots on the leaves, and the leaves are twisted and yellow when severe. In the initial stage, it can be sprayed with a spray of deltamethrin or fluvalinate 2000-2500 times.
The larvae of the fly larvae damage the roots and bulbs of the taro, and the control methods: 1 It is strictly forbidden to use the unfertilized organic fertilizer; 2 the initial stage can be irrigated with deltamethrin or fluvalinate 2000-2500 times.
The main diseases of taro are downy mildew and purple spot, all of which produce fusiform or irregular lesions on the leaves. The downy mildew lesion is yellow-brown, the purple spot disease is purple, and finally the leaves die. These two methods of disease control are generally the same and can be treated concurrently.
Control methods: 1 pay attention to reasonable rotation, clear ditch drainage; 2 early stage of the disease can be used 0.5% lime multi-type Bordeaux mixture (according to 0.5 kg copper sulfate, 1 kg lime, 100 kg water), or 80% chlorothalonil 800 times solution Spray.
6, seed retention technology
There are three common types of taro retention methods:
1 Keep in place. After the harvest of the taro, you should choose plants that are free of pests and diseases, grow well, and special characters to be planted on the spot. Only when the seeds are planted, the plants are planted. This method keeps the bulbs full and has sufficient nutrients. After planting, the plants grow well, but the land is wasted. ;
2 concentrated planting and seeding. When the steamed bread is harvested, the hoes that have been selected for seeding are dug for concentrated planting. This method is used more and saves land, but the growth of the hoe is not as good as that of the place;
3 hanging method to keep seeds. The twigs of the taro leaves to be used for planting are picked up, bundled into bundles, and hung in a cool and ventilated place. This method saves land, but it is labor intensive and plant growth is poor.
Many people in Shantou like to pickle and eat. The taste is very refreshing. It is not only delicious, but also has a very high food value. Therefore, if you like it or haven’t eaten it, you can buy some seeds yourself and try it. Have made an introduction, you can refer to the planting.
