Appropriating panicle fertilizers according to local conditions is one of the important measures to seize the late rice harvest. Panicle fertilizer can be divided into two types of flower-promoting and flower-fertilizing fertilizers according to the application time: sooner or later, the application of panicle fertilizer can be promoted when the rice is just beginning jointing (hand-touching the main stem of the rice plant is changed from flat to garden, young panicle differentiation into the second stage or so). Young panicles differentiate to produce more spikelets, and at the same time, they can promote the formation of large panicles and multiple panicles by increasing the yield of some small tillers and spikes. The preserved fertilizer is when the last leaf (flag leaf) of the main stem has barely emerged but has not yet reached the ear. (Application of panicle fertilizer on the spikelet differentiation of the main stem of the rice plant can reduce the spikelet degradation, increase the seed setting rate, increase the content of chlorophyll, enhance photosynthesis, induce large spikes, increase grain weight and increase yield. Application of panicle fertilizer with less fertilizer, good effect, but the technical requirements are high. Summarize the experience of the region, the application of panicle fertilizer should be based on the level of soil fertility, how much fertility in the early stages, rice seedlings grow good, weather, etc., according to local conditions to see the soil, see fertilizer, See seedlings, see the sky, and have the following flexibility:
1. The basic soil fertility is better, the amount of fertilizer used in the early stage is more, and the rice growing green and the number of seedlings in more fields should not be used to promote flowering fertilizer. On the contrary, if the basic soil fertility is poor, the amount of early fertilizer is less, the growth of rice is poor, and the number of seedlings in the field is insufficient. The application of the preserved fertilizer should also be controlled after the replanting of the field, and the leaf color can be used only when there is a clear fade process. If the field is rehydrated, the plants grow vigorously, the leaf color has been green, and the arbitrarily grown plots are not suitable for applying nitrogen panicle fertilizer;
2. Applying fertilizer varieties, based on years of experiments, it is better to apply fast-dissolving N, P, and K high-concentration compound fertilizers to meet the needs of various nutrients in the middle and late stages of rice growth. In general, the dosage per mu is about 10 kg. For example, if the field is rehydrated, the plant growth potential and yellow leaf color may be appropriately increased by 2-3 kilograms of urea; if the leaf color is green, the amount of fertilizer may not be applied, or only 3-5 kilograms of potash fertilizer may be applied.
3. During late and late rice growth, the weather is long-term, sunny, sunny and sunny. It is beneficial to nutrient conversion and can be applied with more panicle fertilizer. On the contrary, long-term rain and rain, the plant grows green, and it should be applied sparingly or without panicle fertilizer.
At present, the single-season rice in our city has entered into the period of application of flowering fertilizers and continuous cropping rice to enter into the stage of promoting flowering fertilization. Farmers can use the above principles to apply panicle fertilizer based on their own actual conditions of rice growth to win this year's late rice harvest.
