The reasons for the "seating" of Rice
After the big spring rice was planted this year, many farmers came to me and said, "their seedlings have been thrown away for more than ten days. Why are they getting smaller and smaller as they grow?" Our agrotechnical station investigated the growth of seedlings in the whole town, and finally found out the reasons why the seedlings are getting smaller and smaller.
1, the use of herbicides is miscellaneous, such as the use of "wild old" herbicides, the water is deep, the leaves are not long, and some use "strong faith" to produce grass fertilizer, and so on, which inhibit the growth of rice and cause the seedlings to grow smaller and smaller.
2, rotten mud field, rice zinc deficiency, resulting in slow growth, yellow and thin rice.
In view of the above reasons, we propose the following remedial measures:
The main results are as follows: 1. The seedlings caused by herbicides are short, so nitrogen fertilizer is properly applied to lift the seedlings.
2. Due to zinc deficiency in rice, zinc fertilizer should be applied properly.

High-yielding cultivation techniques of Rice "Hybrid glutinous intercropping"
Rice "hybrid glutinous interplanting" refers to the intercropping and cultivation of hybrid rice and glutinous rice. That is, medium-culm hybrid rice and high-culm glutinous rice, making use of the wide row advantage of hybrid rice in wide and narrow rows, increase the planting mode of single-row glutinous rice according to a certain band width, row ratio and width. 1. The main advantages of hybrid waxy intercropping technology 1. Increase rice yield: the results showed that the total yield of hybrid waxy intercropping was 28 kg higher than that of ordinary hybrid rice per 667 square meters and 110 kg higher than that of conventional glutinous rice. 2. Increase income: glutinous rice ratio
