How to prolong the rice seedling age and prepare for drought resistance and rain planting?
In normal years, the seedling age of machine transplanting is about 30 days, that of throwing seedlings is about 40 days, and that of water raising seedlings is about 50 days. If the planting water comes late, it will be faced with extending the seedling age to more than 60 days in order to wait for the seedlings to be planted in water. First, sparse sowing to cultivate long-aged and strong seedlings. That is to say, by expanding the area of seedling bed, reducing the sowing amount per square meter and prolonging the lag tillering period of seedlings, the age elasticity of early sowing seedlings can be effectively increased, the seedling quality can be improved, and the per unit yield can be improved. it can also solve the contradiction of anhydrous transplanting in the early stage.

How to control the "early panicle" of rice?
The Yangtze River and Huaihe River basins have continued to suffer from drought and little rain this year, which has seriously affected agricultural production. From July to August, the phenomenon of early panicle appeared in the rice planting areas north of the Yangtze River and in the Huaihe River basin. The performance in the field showed that the early heading of each hole was 2mur3 ears, which was different from the late tillering for more than 7-10 days, obviously showing "two ear" or "three ear". To make up for the loss of field production caused by "early spike" as soon as possible, the following analyzes the causes of early spike and puts forward rescue measures. The length of rice seedling age is closely related to the phenomenon of early panicle.

Key points of field stage management of mechanically implanted rice
Due to the limitations of seedling age, seedling age, sowing date and plant characters, mechanically implanted rice requires higher tillage quality in transplanting field. At the same time, machine planting realized wide row, fixed hole, fixed seedling and fixed depth planting, which met the population basis of high-yield rice population quality cultivation. Therefore, only if we do not do a good job in the field stage management of mechanically inserted rice, can we ensure the early and stable growth after planting, strive for full panicle, attack large panicle and win high yield. 1. Field preparation: 1. Fine soil preparation: Rotary tillage should be used to kill stubble in field tillage. the depth of rotary ploughing is about 12-15 cm, and the water should be fully absorbed after water.

Total developmental cycle of tea plant
The whole life period of tea tree is from seed germination to senescence and death. According to the growth and development characteristics of tea plant, it can be divided into four biological age periods, namely: seedling stage, juvenile stage, adult stage and aging period. Seedling stage: from seed germination, seedling unearthed to the formation of standing bud at the end of the first growth, it is the seedling stage. Generally speaking, the seeds began to germinate in March of that year and lasted for about 4-5 months until July. Attention should be paid to keeping the soil loose and moist during the seedling stage, so that enough air can be obtained for seed germination.
