Q: The 139****0954 mobile phone sent a message: I am from Sihong County. In our country, there are many shortfalls in wheat and it eventually died. The same applies to rice. Also, the base of the wheat ears lacks a few grains, or the twigs at the base of the ear of a panicle are like squeaking and do not contain particles. What is the reason? Answer: It is normal for a large number of labor deaths in the middle and late stages of wheat and rice growth. Generally speaking, the small tillers with less than three leaves in the jointing stage of wheat and rice cannot form a panicle and will die soon after jointing. These deliveries are invalid deliveries. When the number of peak seedlings is too large and the field group is too large, there are many large branches with more than three leaves at the jointing stage, which cannot be turned into a panicle. Eventually, they will die and belong to invalid tillers. During the cultivation process, wheat and rice should be used according to local conditions. The population is controlled at an appropriate level, and the population in the middle and later periods cannot be too large, or there is too much ineffective delivery, which is not conducive to large spikes and high yields, and it is also likely to cause late lodging. Under normal circumstances, the number of wheat peak seedlings should not exceed 500,000 per acre, and the number of panicles per acre is appropriate at about 350,000; the number of medium-peak rice seedlings should not exceed 300,000, and the number of spikes per acre of 220,000 to 240,000 should be appropriate. Spikelets below the cobs of wheat ears and rice spikes were differentiated and developed late, and they were in a nutritionally inferior position in light, density, and fertilizer. When temperature and other conditions are not suitable for rice, wheat growth and spike differentiation, these spikelets are often stunted.
