Last Updated: 2024/11/06, 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

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 glutinous intercropping technology.

1. Increase rice yield: the results showed that the total yield of hybrid rice and glutinous intercropping was 28 kg per 667 square meters and 110 kg higher than that of conventional glutinous rice.

2. Increase income: the price of glutinous rice is about 15% higher than that of ordinary medium hybrid rice, increase production and income, increase quality and income, increase output value by 50 yuan for every 667 square meters, and increase net income by 35 yuan.

3. It overcomes the problems of low yield per unit area and susceptibility to disease of glutinous rice net cropping, and it is difficult to popularize high quality hybrid rice because of its low net cropping yield, which is beneficial to improve rice quality.

II. Main cultivation techniques and measures

1. Select improved varieties and do a good job in the matching of main and intercropping varieties: hybrid rice selected combinations with moderate plant height, strong adaptability, high yield and excellent rice quality, while intercropped glutinous rice selected varieties with hard culms and lodging resistance, large panicles, many grains and good quality.

2. Rational planting: select semi-arid wide-narrow row or wide-row narrow plant planting and double-plant hybrid rice, one row of glutinous rice every 4 rows, plant spacing of 50 cm to 67 cm, 1200 to 1500 nests between 667 square meters, 6 plants per nest of conventional glutinous rice and 2 plants of hybrid glutinous rice.

3. Scientific fertilization: select special fertilizer for rice, apply 40 kg ~ 50 kg per 667 square meters as base fertilizer, topdressing urea 8 kg ~ 10 kg per 667 square meters at tillering stage, and spray panicle fertilizer at 667 square meters with 100 kg Lipoduo 150 grams mixed with water 50 kg ~ 60 kg.

4. Strengthen the comprehensive prevention and control of diseases, pests and weeds.

5. Other technical points: ① hybrid rice and glutinous rice were sown and planted at the same time. The seeds of ② were treated with chemicals before sowing. Glutinous rice or hybrid rice can be harvested in time by ③, and ratooning rice can be stored.
