How to effectively prevent and control delayed maturity caused by excessive vegetative growth in rice
Rice is the most common staple food for people in China. After rice is husked, it becomes white rice, and ideally a person can eat 700 grams of rice per day. Because rice is rich in protein, it can ensure the body's development and health. Last time we discussed the causes of delayed maturity caused by excessive vegetative growth in rice, and today the editor will explain to you how to prevent and control it.
1. Pay attention to planting density
The planting density of rice has a great impact on the growth and development of rice, and the planting density should not be too sparse or too dense. If the rice planting density is not reasonably controlled, it will not only lead to delayed maturity caused by excessive vegetative growth, but also increase the probability of pests and diseases, which is not only unhelpful but also very harmful to rice. The specific planting density should be determined according to the rice variety and the fertility level of the soil. For example, for hybrid rice, soil with above-average fertility can plant about 20,000 hills per mu, while soil with below-average fertility can increase by 1-2 thousand hills per mu.
2. Rational fertilization
Fertilization should be carried out reasonably according to the growth conditions of rice, and the right remedy should be applied to the right problem, applying whatever kind of fertilizer is needed for the situation. You cannot decide based on your own mood, and you must never apply too much nitrogen fertilizer, or apply only nitrogen fertilizer. Nitrogen fertilizer can indeed promote the crop's symptom development, but applying too much will make it impossible for rice to absorb and convert it all in a short time, and the residue left in the rice causes delayed maturity caused by excessive vegetative growth. Some phosphorus and potassium fertilizer should be applied appropriately to supplement more trace elements for rice.
3. Temperature and humidity control
Rice is a crop that likes water and warmth, so the temperature and humidity in the paddy field must be well controlled. The optimal temperature for rice growth is around 30 degrees, and the water should submerge to a person's ankle. If the humidity and temperature required by rice are not met, it will seriously affect the normal growth of the rice and lead to the occurrence of delayed maturity caused by excessive vegetative growth.
4. Disease control
Rice also encounters many pest and disease situations, such as rice blast, rice planthopper, and so on. These diseases and pests will seriously harm the normal growth of rice. Pests and diseases will destroy the nutrient transport vessels of rice, causing rice to lack sufficient nutrients, fail to mature within the normal time period, and result in delayed maturity caused by excessive vegetative growth. Therefore, diseases must be prevented in advance, and if any disease occurs, you must identify what disease it is, apply the right remedy, and handle it.
The above are the prevention and control methods for delayed maturity caused by excessive vegetative growth in rice that the editor has compiled. There are still some that the editor has not listed one by one, such as ensuring light duration. Delayed maturity caused by excessive vegetative growth in rice is the most likely symptom to appear in rice, and it is also the easiest to prevent and control. As long as the various planting conditions for rice are ensured, the situation of delayed maturity caused by excessive vegetative growth will rarely be seen.
