The latest course of field management techniques and methods of Coix barley

Coix is the seed of Coix of Gramineae. Coix is a popular food crop because of its high nutritional value. Although the taste is similar to that of rice, barley is easier to digest, and it also contains an anticancer agent that can be used to treat gastric and cervical cancer. The area of planting barley is also getting wider and wider, so how to carry out field management after planting? The following editor brings you the field management technology of barley, let's have a look!

1. Ploughing and weeding

After planting barley, we should regularly observe the growth of barley and the number of weeds, and do a good job of weeding in intertillage, and the number of weeding in intertillage should not be less than twice in the whole growth period of barley. The first intertillage should be carried out when the seedlings grow to about 8 cm to promote the tillering of the seedlings. Shallow hoe is the main method for the first time to prevent injury to the root of barley plant and affect nutrition absorption. Then when the seedlings grow to about 18 cm, they are ploughed and weeded again to improve the permeability of the soil. Then the later stage can be carried out together with the topdressing work.

2. Fertilize and cultivate the soil

The number of times of topdressing in the planting of barley rice is the same as that of intertillage, no less than twice, as just said, can be carried out together with intertillage weeding work. When topdressing, we should pay attention to the nutrition proportion and dosage of fertilizer, mainly farm manure for the first time, and the dosage is generally about 1000 kg / mu. The main purpose is to promote the tillering of seedlings and enhance their growth ability. Then the second time can be a little later, when the plant grows to about 36 centimeters. Fertilizer is also based on farm manure, the amount can be appropriately increased by 200-400 kg. Properly cultivate the soil after fertilization, the height of the soil should not be less than 30 cm, improve the root ability of the plant and prevent lodging.

3. Water management

Water management is not only the key to ensure the normal growth of barley, but also the main measure for the high and stable yield of barley. The plant of barley is similar to sorghum and other crops, we all mistakenly think that barley is a kind of dry land crop, but in fact, barley is a kind of swamp crop. In the early stage of the growth of barley, the soil should be kept moist, the seedlings should be strong, and the growth of ineffective tillers should be inhibited by timely drainage after tillering. The heading stage is the critical period for the growth of Coix barley. If there is not enough water, the number of empty grains will increase, and the yield will be greatly affected. Stop watering about 9 days before harvest to facilitate harvesting.

4. Picking leaves for pollination

After the barley has passed the jointing stage, the leaves and tillers under the first branch should be removed in time. Improve plant permeability, facilitate ventilation and heat dissipation, promote the growth of Coix barley, promote the stalk stout, and improve the lodging resistance of the plant. The most commonly used method of pollination of Coix barley is through the wind, but when the wind is low, the pollination rate will decrease significantly. Therefore, we need to do a good job of artificial pollination, in the flowering period of Coix rice, we can use ropes and other tools to vibrate plants, promote pollen spraying, and improve pollination and fruit rate.

The above is a brief introduction of barley field management technology, we must do a good job in water management. A large part of the reason why the yield of many friends' barley is not high is that the barley is planted by dryland crops, which leads to the lack of water, and the growth and development of barley is seriously affected. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
