Latest Field Management Techniques and Methods Tutorial for Coix Seed
Coix seed is the kernel of Coix lacryma-jobi, a plant in the grass family. Coix seed has very high nutritional value and is a relatively popular grain crop. Although its taste is similar to rice, coix seed is easier to digest, and coix seed also contains an anti-cancer agent that can be used to treat stomach cancer and cervical cancer, among others. The area planted with coix seed is also becoming larger and larger, so how should field management be carried out after planting? Below, the editor brings you coix seed field management techniques. Let's take a look!
1. Intertillage and Weeding
After coix seed is planted, the growth of the coix seed and the number of weeds should be observed regularly, and intertillage and weeding should be done well. Throughout the entire growth period of coix seed, the number of intertillage and weeding operations must not be less than two. When the seedlings grow to about 8 cm, the first intertillage should begin to promote seedling tillering. The first operation should mainly be shallow hoeing to prevent damaging the roots of the coix seed plants and affecting nutrient absorption. Then, when the seedlings grow to about 18 cm, carry out intertillage and weeding again to improve soil permeability. Later, it can be carried out together with topdressing.
2. Topdressing and Earthing Up
In coix seed cultivation, the number of topdressings, like intertillage, must not be less than two. As just mentioned, it can be carried out together with intertillage and weeding. When topdressing, pay attention to the nutrient ratio and amount of fertilizer. The first application should mainly be farmyard manure, generally at about 1000 kg/mu. The main purpose is to promote seedling tillering and enhance growth ability. Then the second application can be slightly later, carried out when the plants grow to about 36 cm. The fertilizer should also mainly be farmyard manure, and the amount can be appropriately increased by 200-400 kg. After fertilizing, earth up appropriately. The height of the earthing up must not be less than 30 cm, to improve the root capacity of the plants and prevent lodging.
3. Water Management
Water management is the key to ensuring normal growth of coix seed, and it is also the main measure for high and stable yields of coix seed. The coix seed plant is similar to crops such as sorghum, and everyone mistakenly believes that coix seed is a dryland crop, but in fact coix seed is a swamp crop. In the early stage of coix seed growth, the soil should be kept moist to promote uniform and strong seedlings. After tillering, drainage should be carried out in time to inhibit the growth of ineffective tillers. The heading stage is a critical period for coix seed growth. If water is insufficient, the number of empty grains increases, and yield will also be greatly affected. About 9 days before harvest, watering should be stopped to facilitate harvesting.
4. Leaf Removal and Pollination
After coix seed passes the jointing stage, promptly remove the leaves and tillers below the first branch. Improve plant permeability, facilitate ventilation and heat dissipation, promote coix seed growth, promote thick stems, and improve the plant's lodging resistance. The most commonly used pollination method for coix seed is transmission by wind, but when there is little wind, the pollination rate will drop significantly. Therefore, we need to do a good job of artificial pollination. During the flowering period of coix seed, tools such as ropes can be used to vibrate the plants, promoting the scattering of pollen and improving the pollination and fruiting rate.
The above is a brief introduction to coix seed field management techniques. Everyone must do a good job in water management. A large part of the reason why many friends do not achieve high yields in coix seed cultivation is that they use dryland crop cultivation methods to grow coix seed, resulting in insufficient water for coix seed and very serious impacts on growth and development. That is all for today's introduction. This article is for reference only. Thank you everyone for reading and supporting.
