Biological water-saving technology of rice
Biological water-saving technology refers to the use of the organism's own physiological and genetic potential, in the same water conditions, can obtain more output. Although the research is difficult and the development degree is low, the investment in application is small and the benefit is high. Rice breeders use a large number of germplasm resources obtained for many years to breed a batch of varieties with strong drought resistance through inter-variety hybridization, systematic selection and introduction evaluation, and apply genetic engineering to new variety breeding to continuously provide new hybrid rice combinations with high quality and strong drought resistance and new varieties with greater biological potential for water-saving cultivation.

What if there is fertilizer damage to rice seedlings?
Blindly increasing the amount of chemical fertilizer will cause a variety of physiological obstacles in rice seedlings and make the growth and development of rice abnormal after transplanting. Excessive application of unripe organic fertilizer will also cause poor growth of rice. This kind of physiological obstacle caused by excessive application of fertilizer is called "fertilizer damage". First, there are many reasons for fertilizer damage of rice seedlings, which can be summarized as follows: first, improper fertilization methods. For example, when ammonia or ammonium bicarbonate is applied at high temperature at noon, the volatile ammonia causes fumigation to rice plants.

Lushu No. 7
Lushu No. 7 is a crop of Shandong Academy of Agricultural Sciences, so Nanfeng is the female parent and 918 is the male parent. The variety is resistant to root rot, black spot and stem nematode. The results of two-year regional trials in northern China showed that the yield of fresh potato per mu was 1499.7 kg, 0.02% lower than that of Xushu 18, 455.6 kg per mu of dried potato, 4.07% higher than that of Shu 18, and 294.3 kg of starch per mu, 5.49% higher than that of Xushu 18. The leaves of this variety are all green, and the stem color is green with purple.
