How to prevent empty and blighted rice grains? Master these technical measures
Empty and blighted rice grains refer to unfertilized empty grains and half-empty grains that fail to develop after fertilization, and this has a great impact on rice yield. Therefore, in rice production, in addition to striving for more panicles and larger panicles, it is also necessary to reduce empty and blighted grains, improve the seed-setting rate, and increase the 1000-grain weight in order to obtain high yields. At present, rice is in the grain-filling and ripening stage. To prevent the occurrence of empty and blighted rice grains and achieve the goal of high yield, comprehensive preventive measures must be taken. The specific measures are as follows: 1. Select varieties with good seed setting. Rice varieties differ in physiological morphology, and the seed-setting rate varies greatly.

What causes empty and shriveled soybean seeds
1. Differences between varieties. Mid-to-late-maturing varieties are affected more severely, while early-to-mid-maturing varieties are affected less severely. 2. Drought and waterlogging disasters during the growth period are the key factors causing a high rate of shriveled seeds. The optimal rainfall during the flowering and podding stage of soybeans is 180 mm. During the flowering and podding stage of soybeans, waterlogging is more harmful than drought, especially waterlogging disasters, and the rates of empty and shriveled seeds,...

What are some practical methods to reduce empty shells in sunflowers?
I. Symptom identification 1. Sunflower rust is a major disease of sunflowers, reducing yields by 40-80% in pandemic years. After infection, rust-like spore piles can form on leaves, petioles, stems, flower disks and other parts. When leaves are infected, small brown blisters first appear on the underside of the leaves; these are the uredinia of the pathogen, and after the surface ruptures, brown...

Causes of High Empty and Filled Grain Rates in Hybrid Rice and Control Methods
What should you do if hybrid rice has many empty and shriveled grains? What methods can be used to control the high rate of empty and shriveled grains in hybrid rice? The following methods can be used for control: 1. Adapt measures to local conditions and select hybrid varieties with good recoverability. First, choose varieties with strong tillering ability, sufficient effective panicles, and high seed-setting rate and 1000-grain weight. Second, choose...
