Yannong 19 is the main cultivated wheat variety in Guanyun County. Affected by the warm winter climate in recent years, wheat is generally prosperous before winter. Due to the high plant height and late maturity of this variety, when the per mu output reaches a level of 400 kg or more, it is easy to cause high yielding lodging, especially in the middle and later periods when the typhoon and rainstorm are encountered. In view of this situation, the promotion and application of "Spring Spring dwarfing abundance" during the re-green jointing stage of wheat yielded significant effects.
In 2010, the experiment was conducted at Linzhuang Village, Xiche Township. The soil was clay loam soil, and the soil fertility was medium. The variety was Yannong 19, and the cornices were drought and flood. On March 25th, the trial was carried out to treat 50 grams of “Spring Spring dwarf strong†sprayed per acre, and 50 grams of “Spring Spring dwarf strong†sprayed per acre (50 grams on April 15). The external treatment 3 is a spray water control. Survey on March 25th, the growth of the wheat field was consistent, the plant height was 42.9 cm, the leaf age was 7.9 leaves, and the total stem number was 1.134 million.
On April 15th, the treatment 1 and treatment 2 plant heights, the first internode length, and the second internode length were 52.5 cm, 6.2 cm, and 8.6 cm, respectively, 3.1 cm, 0.7 cm, and 1.2 cm shorter than the control. Spraying “Spring Spring dwarfing abundance†at the jointing stage has the effect of significantly inhibiting the length of the internodes, and the control effect is obvious.
Investigation on May 10th showed that treatment 2 had the most obvious effect on control of Wang, and it had obvious inhibitory effect on the growth of each node, and it was safe to heading, and tillering was not affected by tillering. One plant height of 83.5 cm was treated, 2 cm higher than treatment 2 and 11.8 cm shorter than the control.
In the field survey at the ripening period in June, the treatment 1 and treatment 2 plants were significantly dwarfed, and no lodging was observed, while the control community had a level 3 lodging and serious lodging.
The results of the experiment showed that “Spring Spring dwarf strong†was sprayed on the green jointing stage, and the control effect was obvious, which could effectively prevent the lodging of wheat. For the severely prosperous plots of plants, spraying again at the booting stage is a safe, reliable way with strong resistance to lodging.
