Rice can increase production by using wins

The ability to increase production after the use of rice has become a consensus among many users. The main principle is that the drug action of hexaconazole regulates the growth mechanism of rice and thus increases the yield.

In the first stage, rice is selected from high-quality adobe and mixed with bactericidal and insecticidal powder. 7-10 days before transplanting with 30 kg of watering can with a pack of 3 kg (3 g) with foliar fertilizer on an acre field Evenly spray the seedlings should pay attention to lowering the nozzle as much as possible to spray the liquid to the soil surface. In the next 2 to 3 days, it will be found that the seedlings are not long and the leaves of the seedlings are widened and thickened. This is normal. Because of the pharmacodynamic effect of hexaconazole, the apical effect of the seedlings is inhibited. The effect of the growth of the foliar fertilizer is inhibited. The seedlings stop growing and the photosynthesis of the leaves is enhanced to provide a large amount of growth nutrients to promote the seedlings above the soil surface. I want to flank the growth (increasing the width and thickness of the leaves). The soil surface promotes the development of the root system, making the root hair longer and more laid a better foundation for providing water and nutrients to rice in the future. It should be noted that transplanting must be carried out 7 days after application to avoid the impact of the seedlings during the efficacy period.

The second stage of the tillering period 10 to 15 days after transplanting the seedlings (about half a foot to one foot high in the rice seedlings) spray 3 pots per acre (30 kg). Each pot is matched with 3 grams of winning power. . At this stage, the main function is to increase the number of rice seedlings, increase the photosynthesis effect, and provide more nutrients. At the same time, the use of hexazolol to control the shoots makes the nutrients to the flag leaves and stems and the roots to promote roots, strong stems and promote the flag leaves. Prosperous role. Four days after spraying, it was found that the roots were more developed and the stems became thicker.

Before the third stage of the break (booting stage), the stems and leaves of the rice were evenly sprayed. Similarly, 3 pots (30 kg / pot) of spray liquid per acre are used for each pot with a win of 3 grams, and the US state gold point (killing rice planthopper) 4 grams. The most important role of this stage is to prevent the occurrence of the above pests and diseases before the disease is broken. At the same time, it also supplies enough nutrients to the ears to increase the amount of rice.

The fourth stage is at the beginning of the season. The heading stage is also 4 days after the flowering period (Note: the flowering period can not be sprayed, it will cause the rice flower to fall off). After all the rice is formed, the spraying power will still be 3 pots per acre, and each pot will have a winning power of 3 grams. To prevent the occurrence of rice blast, the blasting power is accompanied by the prevention of rice blast by Smith Barne. The most important use of this stage is to control the growth of rice so that its nutrients are fully supplied to each rice grain, and finally the rice grains are full to increase production.
