How much is a catty of Niu Dali seeds?
The price of snail seeds is about 180 yuan, ranging from 150 to 150 kg, but the price varies greatly due to the difference of seed quality, variety, origin and market. At present, Niu Dali has not been industrialized in China, and many growers mistakenly think that there will be a bumper harvest once planted. But they don't know that there are many germplasm sources of Millettia speciosa, and there are certain differences in morphological characteristics and yield of Millettia speciosa from different sources. Only by selecting suitable varieties with high quality and high yield can we have a successful harvest, otherwise, we may fail. It can be said that the provenance determines the success or failure of planting.
Sowing method of Millettia speciosa
1. Seed collection: Millettia speciosa seeds mature about 10 every year. When all the pods are yellow but not cracked, pick them, then dry them in the sun, remove the pods and remove the bad seeds.
2. Germination accelerating treatment: soak the seeds of Millettia speciosa in warm water at 55℃ for 10~ 15 minutes, then take them out and soak them for about 7 hours. After the seeds fully absorb water, add a proper amount of fine sand and stir evenly. After stirring evenly, sprinkle a layer of fine sand and sow after the seeds turn white.
3. Weeding and killing insects: Before sowing vigorously, spray 500 ml of 1.8% avermectin EC, 80 ml of glyphosate and 25 kg of fine sand mixture per mu for weeding and killing insects. After 3 days, apply base fertilizer, and then divide the cultivated land.
4. Sowing method: the row spacing is 25cm, and the ditch dug should not be too deep. After the seeds are sown, cover them with a thin layer of screened soil. The sowing amount per mu is about 0.6 kg, and the density is 40,000-60,000 plants.
5. Post-sowing management: After sowing, the cows should be watered and fertilized vigorously, especially when sowing. To keep the moisture of seeds, the fertilizer concentration should not be too high to prevent the seeds from burning out, and the seedlings will emerge about 13 days after sowing.
Planting method of Millettia speciosa
1. Transplanting management: The planting density of Millettia speciosa is about 300~500 plants/mu, and the planting time should be in the afternoon when the sun is weak. It is best to bring the earth lump into the hole, and the planting depth should be higher than the unearthed lump surface 1cm or even. After planting, water should be poured through it.
2. Weeding in time: Avocado grows slowly in the early stage of planting, and weeds between ridges can be removed manually or sprayed with herbicides. When spraying herbicides, we should pay attention to spraying herbicides carefully in still wind to prevent herbicides from floating on cattle grass plants.
3. Fertilizer and water management: Niu Dali is drought-tolerant and waterlogging-tolerant. About a month after planting, you can start topdressing after pulling out the branches. Pour 2 kg of compound fertilizer and 400 kg of water per mu. About 3 months after sowing, the total amount of topdressing per mu is 40 kg, and then fertilization is once a year every 10 month.
4. Pruning and pruning: For plants that are not used for reproduction, strong branches should be cut off. For the propagated plants, spray a bottle of 30 kg of water on the leaves of Yuhualing 2. After spraying for 2-3 times continuously, the plants planted in March-April can enter the flowering period in June-September.
5. Sparse flowers and promote fruit: spray Yuhualing No.2 once before flowering to promote flowering and pod setting, so that a large amount of nutrients can be supplied to underground roots and roots. Spraying Yuhualing No.5 after beginning of autumn promoted the rapid rooting and continuous expansion of Niudaling.
6. Pest control: spraying 50% carbendazim wettable powder and 80% mancozeb 600 times each can control LEPIDOPTERA pest leaf spot, and spraying 5% avermectin EC, 5% avermectin chlorpyrifos granules or 2.5% avermectin hexaflumuron EC 1000 times can control LEPIDOPTERA pests.
7. Harvesting and processing: Millettia speciosa should be harvested when the soil is dry in autumn and winter. After deep ploughing between rows with a cultivator, you can harvest it manually, and you can also dig potatoes manually if you have no conditions. After harvesting, it can
