Strong planting technique of cattle

Niu Dali is a plant belonging to the genus of Leguminosae, also known as pig foot, golden bell root, mountain lotus root, inverted golden bell, Dali potato, etc. It has the effects of strengthening yang, nourishing kidney, strengthening tendons and activating collaterals, calming liver, moistening lung, etc., and has high cultivation value. Let's take a look at the planting technology of Niu Dali together!

Can cattle be planted?

Cows can be grown vigorously. Cattle Dali has not been industrialized in China, so many growers often make mistakes in understanding that once cattle Dali is planted, it will be successful harvest. However, cattle Dali has many different germplasm sources, and there are certain differences in morphological characteristics and yield of different cattle Dali provenances. Only the varieties with excellent quality and high yield can be successfully harvested, otherwise they may fail.

Seed selection of Dawley cattle

1. Seed seedlings: Niu Dali seed seedlings are formed by seed germination. Generally, there is only one taproot. After the taproot is cut off, the fine roots sent out are not easy to expand into potatoes. The seedling characters are high and irregular, and the yield is not guaranteed. Moreover, there are many forks, slow growth, low yield and poor quality, and the plants planted for more than two years will flower and bear fruit, while the quality of underground tubers of plants used for flowering and bearing is relatively poor. Generally, it takes 4~5 years for seedlings to form yield.

2. Tissue culture seedlings: The tissue culture seedlings of Niu Dali are produced in batches, grow neatly, have excellent characteristics, have a large number of roots, and can expand into tubers.

3. Cuttings: Cuttings have great advantages in cattle seedlings. Cuttings are relatively easy to collect than seeds and can maintain the excellent characteristics of female parents. The content of effective components is high. Compared with seedlings, the yield is faster, the tuber is more, and the quality is good. Generally, the yield can be formed in 1~2 years. The advantage is obvious.

Cattle are vigorously planted ready

1. Seedling training: The seedlings of Niu Dali after nursery need to slow down before planting. After placing, spray 500 times of carbendazim solution to prevent diseases. The seedlings are trained under the shade for about one week, and drench once a day in the morning. No conditions can be in the shade of the seedlings, regular watering.

2. Selection of land: Niu Dali needs more water during seedling stage, so it should ensure soil humidity, but it is not resistant to waterlogging. Drainage should be carried out in time in rainy season. There should be no accumulated water in the furrow. Therefore, as long as it is not paddy field when transplanting, it is generally suitable for planting.

3. Soil preparation: cattle vigorously select the land and then weed, deeply plow the land, rake the land, loosen the soil in the place ready for planting if machine ploughing cannot be carried out, and the ploughing depth is 0.5 meters. Then according to the terrain excavation drainage ditch, along the contour line from 1.5~1.8 meters wide, 0.6 meters high or so large ridge, high ridge. A pit of 1 m square and 0.5 m deep was dug at the planting point on the slope.

4. Base fertilizer: when preparing the soil, the base fertilizer is sufficient, 1~2 tons of organic fertilizer per mu and about 100 kilograms of calcium superphosphate are mixed evenly, and then spread on the ground, then rotary tillage, ridging, or ridging is spread on the top of the ridge. Subsequently, it is recommended to cover agricultural film, black film is good, thickness is more than 0.014 mm, width is determined according to ridge width and ridge height.

Cattle-Dali Planting Technology

1. Transplanting management: planting density is 300~500 plants/mu, planting time should be selected in the afternoon when the sunlight is weak, if cloudy, planting can be carried out all day, holes should be drilled on the plastic film according to the plant spacing, and the nutrient bowl should be torn at the edge of the hole during planting, and then the seedlings should be brought into the hole with soil lumps to prevent the soil lumps from spreading. The planting depth should be 1 cm or even from the soil lumps. Where conditions permit, drip irrigation can be used to irrigate, water pipes can be pre-laid on the ridge top, and then plastic film can be covered to supplement water according to soil and weather conditions in time to achieve water-saving purposes.

2. Timely weeding: cattle grow slowly in the early stage after planting. Weeds between ridges can be removed manually or by spraying herbicides to prevent weeds from competing for fertilizer and water with cattle seedlings. When spraying herbicides, pay attention to spraying carefully under static wind to prevent herbicides from floating to cattle plants.

3. Fertilizer and water management: cattle are drought-tolerant and waterlogging tolerant, especially at seedling stage. In rainy weather, ditch drainage should be conducted in time to prevent flooding. About 1 month after planting, after the branches are taken out, topdressing can be started, and compound fertilizer 2 kg/mu mixed with water 400 kg/plant can be irrigated. About 3 months after planting, the total amount of topdressing per mu is 40 jin (urea and compound fertilizer are mixed evenly), a small handful of compound fertilizer is applied between every two seedlings, and fertilizer is applied once a year around October.

4. Pruning and pruning: For vine type or small shrub type cattle, the growth of branches should be controlled through pruning management, so as to make underground potatoes grow more, grow faster and increase yield. For plants that are not used for propagation and planting, strong branches should be thinned to inhibit vine growth, plant height should be maintained, and the earlier pruning, the better, and the root growth of nutrient supply should be promoted. For the plants with seeds reserved for reproduction, in addition to pruning in the early stage, a bottle of Yuhualing No.2 should be mixed with 30 kg water for foliar spraying. After continuous spraying for 2~3 times, the plants planted in March ~ April can enter flowering stage in June ~ September.

5. Thinning flowers and promoting fruits: Niu Dali thinly cuts some flower buds when flower buds grow out, and the number of flower buds should not be too many, and the number of branches of plants should be maintained. Yuhualing No. 2 is sprayed once before flowering to promote flowering and pod setting, and to promote a large number of nutrients to concentrate on the growth of underground rhizomes. After the beginning of autumn, Yuhualing No. 5 was sprayed to promote rapid rooting and continuous expansion of Daoli, and corresponding fertilizers were applied according to the growth conditions of leaves and rhizomes of Daoli, so that Daoli could obtain high yield.

6. Disease and pest control: Adult plants of cattle are generally not easy to be harmed by diseases and pests, but seedlings may have a small amount of leaf spot disease under high temperature, rainy and humid conditions, which can be controlled by spraying 600 times of 50% carbendazim WP +80% mancozeb. At the same time, the seedlings of DaLi cattle are vulnerable to lepidopteran pests, which can be controlled by 1000 times solution of 5% abamectin EC, 5% abamectin chlorpyrifos granule or 2.5% abamectin fluorouracil EC.

7. Harvesting and processing: The harvesting time of cattle should be harvested when the soil is dry in autumn and winter. If conditions are available, the ploughing machine can be deeply ploughed once between rows, and the manual harvesting shall be carried out after loosening. If conditions are not met, the potatoes shall be directly dug manually. After harvest, it can be stored in cold storage at 0~5℃ for half a month, and can also be sliced and dried, fresh sliced and vacuum packaged, and made into beverages.
