How to Read the Corn Milk Line? A Detailed Guide to Identification Methods
Compared with traditional grain crops such as rice and wheat, corn has strong drought tolerance, cold tolerance, and tolerance of poor soil, as well as excellent environmental adaptability. A corn kernel consists of four parts: the pericarp, the endosperm, the germ, and the root cap. So, how do you read the corn milk line?
1. How do you read the corn milk line?
The corn milk line is the boundary between the germ of the corn kernel (that is, what is commonly called the corn navel, which can be used to press oil——corn germ oil) and the endosperm (that is, the main edible part of corn, which is rich in starch), while the black layer (or black-layer) is the boundary between the corn kernel and the cob. When the black layer of the corn kernel begins to appear and gradually darkens, it indicates that the corn is approaching maturity.
2. Corn cultivation techniques
1. Choose excellent varieties
To achieve high yields when growing corn, you should choose corn varieties that tolerate poor soil, have good yield performance, are suitable for dense planting, have strong disease resistance, and have passed national review and approval.
2. Land preparation
Land preparation methods differ depending on the soil, so you should choose plots with a soil structure suitable for growing corn. During land preparation, do not work continuously; carry out deep plowing of the plot.
3. Sowing
In the process of growing corn, sowing should be decided according to the thickness of the soil. In addition, sowing time is also crucial; you should choose a season with suitable temperature and suitable humidity. When sowing, also pay attention to uniform plant spacing and the firmness of the soil cover. If sowing seedlings, sow a little later according to the actual situation of the growth period, so as to obtain a relatively large temperature difference during the grain-filling stage, thereby increasing the accumulation of substances and promoting nutrient supplementation during its growth and development period.
4. Dense planting
Corn yield is determined by soil fertility, water sources, variety, weather, and so on, and appropriate dense planting can improve yield. However, it should still be decided according to the conditions of the planting site, the characteristics of the variety, the climate type, and so on.
5. Strengthen field management
Within ten days after sowing corn, inspect the seedlings and fill in gaps, and promptly deal with bad sprouts. When establishing the stand, remove diseased seedlings, mixed seedlings, and small seedlings to ensure an adequate number of plants.
In addition, extensive practice has shown that delaying the corn harvest can increase yield by 750-1500kg/hm2, with the 1000-grain weight increasing by more than 15%. When the grain moisture content is less than 14%, choose a dry, well-ventilated site for storage.
