How to store mung beans without sprouting and how to store mung beans without worms
Mung beans and adzuki beans are the treasures of grain, so how to preserve these two kinds of grain? Mung bean and adzuki bean are easy to change color because the seed coat contains more tannins and polyphenoloxidase, which is easy to oxidize and change color under the conditions of air, light, water and temperature. The greater the moisture, the warmer it is.

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.

How to Sprinkle Compound Fertilizer at Rice Jointing Stage
In the jointing stage of rice, we usually need to apply fertilizer for 1~2 times. In previous years, we used urea. This year, we changed to fertilizer granulated by high tower. This is a compound fertilizer with high nitrogen content and low phosphorus and potassium content. The fertilizer particles are round in shape, with holes in them and light in proportion. Before fertilizing, we first discharged flooding water, then scattered compound fertilizer particles on the soil surface, and then released water back to the field. After the water layer is full, we find that some fertilizer particles appear on the water surface. These floating fertilizer particles are blown to one side with the wind, and some stay in the corner where the wind is weak.

Management measures during jointing and panicle growth of rice
The jointing and long panicle stage refers to the period from jointing and young panicle differentiation to pre-heading, and the medium rice generally lasts for 25-36 days. 1. During this period, some tillers gradually died, and the total number of tillers decreased compared with the previous period, so it was an important period for tiller protection and panicle increase.

Management measures for jointing and long panicle stage of Rice
At present, the growth of rice in the city has gradually entered the stage of jointing and panicle growth, which is not only an important period for the transformation from vegetative growth to reproductive growth, but also a key period to determine yield. To do a good job in the field management of rice in the middle and later stage is very important for protecting full panicle, attacking large panicle, shaping high-yield plant type and setting up high-yield shelf. 1. Seedling characteristics according to the survey on July 21, the average leaf age of mechanically implanted rice was 12.31, 0.49 more than that of the same period last year, the average leaf age of direct seeding rice was 10.31, 0.56 more than that of last year, and the total number of tillers was 38.63.

Management of booting stage of Rice in August
1. Field management at booting stage after good vegetative growth in the early stage, rice enters the reproductive growth stage in the middle and later stage. Strengthening the management of water and fertilizer in this stage is very important for high yield. The skillful application of panicle fertilizer depends on the field growth of rice: the number of stems per mu is too much, the number of stems per mu is not applied, the number of stems per mu is insufficient, and fertilization in the land with yellow leaves can increase yield obviously. 1. Application of panicle fertilizer: around August 5, the land without early panicle fertilizer (mid-late July) has yellow leaves at this time, but urea 5-7 per mu.

Eight measures for safe use of Rice
1. Reasonable selection of varieties. Rice blast is the main disease affecting harvest, and the difference of resistance among different varieties is very obvious. The selection of varieties with strong resistance is one of the most effective prevention measures. In the old rice blast area and the cold soaking field in the shade, first, the resistance of the varieties should be carefully understood when selecting and purchasing seeds; second, the new varieties can only be planted in a small amount before being popularized; third, imported Fuji No. 1 should be used for prevention in the early stage of the disease and the stage of booting and heading. Where the humidity is high in the mountain area, it is not suitable for late hybrid rice to choose and purchase two-line hybrid late rice combinations to prevent rice false smut.

Rice dwarf disease
The symptoms were mainly distributed in the southern rice area. Also known as rice common dwarf disease, general dwarf, green dwarf and so on. After the rice was susceptible from seedling stage to tillering stage, the plant was dwarfed, the tillers increased, the leaves were thick green and stiff, and the diseased rice could not heading and fruiting in the later growth stage. The symptoms of diseased leaves can be divided into two types. The white spot type appeared dotted yellow-white spots parallel to the leaf vein on the leaf blade or on the leaf sheath, especially at the base. Dots appeared in the new leaves above the initial diseased leaves, but not in the following old leaves. In the twisted type, the extraction of the heart lobe is distorted in the case of lack of light.

Rice k you 926
Hybrid rice K you 926 was developed by Rice Sorghum Research Institute of Sichuan Academy of Agricultural Sciences in 1993 using K17A (identified) bred by the institute and Luhui 926. In 1995, Chongqing Agricultural Technology extension Station and Chongqing seed Station were jointly introduced into our city. The average yield per mu of medium rice plus ratooning rice in 1996, 1998 and 1999 was 3.36% higher than that of Shanyou 63, which was 3.36% higher than that of Shanyou 63 in 1995-1999 in Jiangjin, Changshou, Qijiang and Jiulongpo District of our city.

The reasons for the "seating" of Rice
After the big spring rice was planted this year, many farmers came to me and said, "their seedlings have been thrown away for more than ten days. Why are they getting smaller and smaller as they grow?" Our agrotechnical station investigated the growth of seedlings in the whole town, and finally found out the reasons why the seedlings grew smaller and smaller, mainly as follows: 1. Herbicides were used as miscellaneous herbicides, such as using "wild old" herbicides, being flooded deeply, not growing heart leaves, and some applying "strong faith" grass fertilizer, etc., which inhibited the growth of rice and caused the seedlings to grow shorter and smaller. 2. Rotten mud fields, zinc deficiency in rice

High-yielding cultivation techniques of Rice "Hybrid glutinous intercropping"
Rice "hybrid glutinous interplanting" refers to the intercropping and cultivation of hybrid rice and glutinous rice. That is, medium-culm hybrid rice and high-culm glutinous rice, making use of the wide row advantage of hybrid rice in wide and narrow rows, increase the planting mode of single-row glutinous rice according to a certain band width, row ratio and width. 1. The main advantages of hybrid waxy intercropping technology 1. Increase rice yield: the results showed that the total yield of hybrid waxy intercropping was 28 kg higher than that of ordinary hybrid rice per 667 square meters and 110 kg higher than that of conventional glutinous rice. 2. Increase income: glutinous rice ratio
