    How to strengthen the tillering rate of Rice at Seedling stage

    Early application of tillering fertilizer and appropriate application of tillering fertilizer nitrogen nutrition play a leading role in rice tillering, and the amount of fertilizer applied at tillering stage is 25% of the whole growth period, so early application of available nitrogen tillering fertilizer to quickly turn black leaves is the main measure to promote tillering in the early stage.

  • Fertilizer application of mechanically inserted rice

    Fertilizer application of mechanically inserted rice

    The total amount of fertilization of mechanically planted rice is about the same as that of artificial hand-planted rice. But how to apply it in different periods, machine-planted rice is different from hand-planted rice. The main reason is that the tiller node position of mechanically inserted rice is low and the tillering stage is long. in order to control the panicle number of the population within a suitable range, the key point of fertilizer operation should be to improve the application period of tillering fertilizer in order to adjust and utilize the most suitable tiller node position and control the mid-stage population. and increase the application of panicle fertilizer, promote spikelet differentiation and strive for large panicles. The characteristics of machine-planted rice and hand-planted rice determine the base and tiller fertilizer of machine-planted rice.

  • Changing the phenomenon of "six more and six less" is the key to improve the per unit yield of double cropping rice in Jiangxi.

    Changing the phenomenon of

    Rice is the most important food crop in Jiangxi. Improving the per unit area yield of double-cropping rice is an important way to ensure Jiangxi's status as the main grain producing area and to ensure Jiangxi to make greater contribution to national food security. In recent years, although the per unit yield of double-cropping rice in Jiangxi has increased steadily, the phenomenon of low yield has not changed much. Compared with neighboring Hunan, each 667m2 is lower in 50~60kg. The analysis shows that the phenomenon of "six more and six less" is the main reason for the low per unit yield of rice in Jiangxi. The main results are as follows: 1. the amount of sowing is more and the amount of seed is less. Cultivate

    Effect and Application of paclobutrazol on Rice

    Paclobutrazol is a highly active plant growth retarder and broad-spectrum fungicide. The physiological effects of pp333 in the world and MET in China are mainly dwarfing, promoting tiller and improving stress resistance. Moreover, it is a simple, easy and effective measure to increase yield by turning green quickly, tillering early, increasing the number of effective panicles, seed setting rate and 1000-grain weight. After experiments in recent years in various parts of Liaoning Province, it was found that the higher zole yield of rice seedlings had the following changes compared with the control: 1.
