Why do sunflower seeds produce empty seeds?
Why do sunflower seeds produce empty seeds? Please give an introduction to the main reasons why planting sunflower will produce empty grain can refer to the following: 1. Empty grain caused by drought: Sunflower is a crop with strong drought resistance. However, the water requirement is the largest from the formation of flower disc to the end of florescence, accounting for about 60% of the water requirement in the whole growth period.

Why does rice produce empty chaff and how to prevent it?
Why does rice produce empty chaff and how to prevent it? Please give a detailed introduction. Under normal circumstances, the rate of unblighted rice grains is 10%-20% in general, and 40% in severe cases, which has a great impact on rice yield. The main results are as follows: 1. the formation reason of rice empty grain rate is mainly affected by three factors. 1. Angry.

The cause of empty chaff of soybean
1. The difference of breed. The occurrence of middle and late maturity varieties was more serious, while that of early and middle maturity varieties was lighter. two。 Drought and waterlogging during childbearing period are the key factors leading to high grain rate. The best rainfall at the flowering and pod stage of soybean is 180 mm. In soybean flower and pod period, waterlogging damage is more harmful than drought, especially waterlogging disaster, empty grain rate,.

Technical measures to prevent the production of empty chaff grains in Rice
The empty grain of rice refers to the empty grain that is not fertilized and the half-empty grain that can not develop after fertilization, which has a great influence on the yield of rice. Therefore, in rice production, in addition to striving for more panicles and large panicles, it is necessary to reduce empty grains, increase seed setting rate and increase 1000-grain weight in order to obtain high yield. At present, it is the filling and fruiting stage of rice. In order to prevent the production of empty grains and achieve the goal of high yield, comprehensive preventive measures must be taken. The specific measures are as follows: 1. The physiological forms of good fruiting varieties are different among rice varieties, and the seed setting rate varies greatly.

Management of jointing and booting stage of Rice
The management of jointing and booting stage in the field, 50% of the main tillers lengthened 1m ~ 2cm, and the shape of the main tillers changed to the jointing stage. 50% of the flag leaves are at booting stage when they are all exposed to the leaf sheath. This period is the time when rice needs the most water in its life, such as dry water for a long time, which will affect the formation of panicles, with small spikes and more empty chaff. However, it can not be flooded in deep water, but should be irrigated frequently in shallow water, properly open fields, promote root growth, achieve deep roots and luxuriant leaves, and increase the number of ears and grains.

Guard against the occurrence of rice sheath blight under high temperature and humidity
Sheath blight, also known as sheath blight, rice sheath blight has a great impact on its growth and development, not only weakening the absorption capacity of roots, but also affecting leaf photosynthesis, resulting in an increase in empty chaff grains, a decrease in 1000-grain weight and a decrease in yield. Therefore, attention should be paid to the prevention and control of sheath blight in production. The main symptoms, occurrence characteristics and control methods of this disease are introduced below for reference. The main symptoms of rice leaf sheath infection produce dark green water-immersed spots with blurred edges near the surface of the water, then expand in oval or moire shape, and grayish green in the middle.

Emergency measures for Cotton Bud and Boll shedding
When cotton grows in high temperature and rainy climate, a large number of buds and bolls will fall off, resulting in plant height, size and emptiness, resulting in a large reduction in yield. According to the causes of different shedding, corresponding emergency remedial measures can be taken. For cotton fields that have been dry for a long time without rain and can not be watered, the leaves of cotton plants are thin and small, the leaves are light green and yellow, the chaff of buds is small, heavy rain falls heavily, light rain falls less, and no rain falls gradually. Remedial measures: 200 grams of multi-element boron fertilizer per mu plus 20 ml of Fengchengning, evenly sprayed with 50 to 60 kg of water, interval

Four Key Points about Rice Fertilization
First, pay attention to applying enough organic fertilizer. Organic fertilizer contains various nutrients, which can improve soil ventilation and fertilizer absorption and water retention characteristics, promote stable growth of rice plants, and obtain high yield and high quality. Organic fertilizer is mainly used as base fertilizer, 30 - 40 loads of decomposed soil fertilizer per mu, or 30 - 40 kg of cake fertilizer, and 40 - 50 loads of human and livestock manure can be applied before ploughing. Second, attention should be paid to controlling nitrogen fertilizer. Excessive application of nitrogen fertilizer in rice will not only cause increase of ineffective seedlings, turning green, lodging, intensification of diseases and insect pests, but also lead to more empty grains and lower seed setting rate, which will affect rice yield.

Four effects of High temperature on Rice
The temperature requirements of rice are different in each growth and development stage, and there is an optimal temperature. If the critical temperature exceeds the upper or lower limit, the growth and development of rice will appear abnormal phenomenon, that is, physiological obstacles. Therefore, attention should be paid to the effect of high temperature on rice. 1. Effect of high temperature on each growth stage of rice. 1. Heading and flowering stage. Generally, the temperature of 25-30 ℃ is suitable for rice at heading and flowering stage. A large number of empty grains will appear when the temperature is lower than 25 ℃ or higher than 30 ℃. At the same time, the high temperature
