The Latest Control Methods for Rice Delayed Maturity Due to Excessive Vegetative Growth
Rice is the most common staple food for people in our country. After rice is hulled, it becomes white rice. Ideally, a person can eat 700 grams of cooked rice per day. This is because rice is rich in protein, which can ensure the body's development and health. Last time we discussed the causes of rice delayed maturity due to excessive vegetative growth. Today, the editor will explain to you how to control rice delayed maturity due to excessive vegetative growth.
1. Pay attention to planting density
The planting density of rice has a great influence on the growth and development of rice. 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 due to 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 depend on 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. Reasonable fertilization
Fertilization should be carried out reasonably according to the growth conditions of the rice, and the right remedy should be applied to the right problem. What kind of fertilizer to apply depends on the situation. You cannot decide based on your own mood. You must not apply excessive nitrogen fertilizer, or apply only nitrogen fertilizer. Nitrogen fertilizer can indeed promote the symptomatic development of crops, but applying too much will make it impossible for the rice to absorb and convert it all in a short time. Remaining in the rice plant causes delayed maturity due to excessive vegetative growth. An appropriate amount of phosphorus and potassium fertilizer should be applied to supplement more trace elements for the rice.
3. Temperature and humidity control
Rice is a crop that likes water and warmth. The temperature and humidity in the paddy field must be well controlled. The optimum temperature for rice growth is around 30 degrees, and the water should submerge to a person's ankles. If the humidity and temperature required by rice are not met, it will seriously affect the normal growth of the rice and lead to delayed maturity due to excessive vegetative growth.
4. Disease control
Rice also encounters many pest and disease situations, such as rice blast, rice planthopper, etc. These diseases can seriously harm the normal growth of rice. Pests and diseases can damage the nutrient transport vessels of rice, causing the rice to lack sufficient nutrients, fail to mature within the normal time period, and result in delayed maturity due to excessive vegetative growth. Therefore, diseases must be prevented in advance. If any disease occurs, you must identify what disease it is, apply the right remedy, and handle it.
The above are the control methods for rice delayed maturity due to excessive vegetative growth compiled by the editor. There are still some that the editor did not list one by one, such as ensuring light duration. Rice delayed maturity due to excessive vegetative growth is the most likely symptom to appear in rice, and it is also the easiest to control. As long as the various planting conditions for rice are ensured, delayed maturity due to excessive vegetative growth will rarely occur.
