Embodiment 1

[0019] The control effect of the fulvic acid of embodiment 1 different purity to transplanting paddy field main weed

[0020] The inhibitory effect of different purity fulvic acid on the seedlings of barnyardgrass, stephenia and bermudagrass was determined by agar culture method. Add 300 mL of 0.2% agar into a disposable plastic cup, the height of the plastic cup is 13 cm, and the diameter of the cup mouth is 9 cm. After the agar is solidified, 25 barnyardgrass, barnyardgrass and bermudagrass seeds are embedded on the display. Experimental design of 5 fulvic acid purity treatments:

[0021] T1: Fulvic acid with 20% purity;

[0022] T2: Fulvic acid with 40% purity;

[0023] T3: Fulvic acid with 60% purity;

[0024] T4: 80% pure fulvic acid;

[0025] T5: 100% pure fulvic acid.

[0026] The amount of fulvic acid with different purity is 0.2g, the flooding height is 5cm, the fulvic acid used in the test is analytically pure, the control group uses water as a blank, and the t...

Embodiment 2

[0031] Example 2 The control effect of fulvic acid salts on the main weeds in transplanted rice fields

[0032] The weed control effects of different fulvic acid salts on barnyardgrass, stephenia, and bermudagrass seedlings were measured, and the test conditions were the same as in Example 1. The fulvic acid salts tested include potassium fulvate, sodium fulvate, magnesium fulvate and calcium fulvate, all of which have a solubility of 2g / L and a flooding depth of 3cm.

[0033] Table 2 Control effect of different fulvic acid salts on barnyardgrass, stephenia and bermudagrass seedlings

[0034]

[0035]

[0036] The test results show that different fulvic acid salts have a strong control effect on barnyard grass, stephenia and bermudagrass. Among them, potassium fulvic acid and sodium fulvic acid had the best control effects on the main weeds in transplanted rice fields, followed by magnesium fulvic acid, and calcium fulvic acid was the lowest. The control effects of pot...

Embodiment 3

[0037] Example 3 The effect of fulvic acid application rate on the main weeds in transplanted rice fields

[0038] The field test was used to determine the weed control effect of the application amount of fulvic acid on the main weeds in the transplanted rice field. The purity of fulvic acid used in the test was 30% to 60%. The conventional fertilization in the test is 30kg / mu, and the conventional fertilization in the test includes the following nutrients: the content of inorganic salt (K or Na) is 5% to 15%, the content of organic matter is 60% to 80%, and the content of total nitrogen is 3% to 5%. The phosphorus content is 0.3% to 0.5%.

[0039] Experimental design 10 treatments of fulvic acid application rate:

[0040] CK: conventional fertilization;

[0041] T1: Conventional fertilization + 30% fulvic acid with a purity of 10Kg / mu;

[0042] T2: Conventional fertilization + 30% fulvic acid with a purity of 20Kg / mu;

[0043] T3: Conventional fertilization + 30% fulvic a...

Abstract

The invention belongs to the technical field of plant protection and fertilizer, and more specifically relates to applications of fulvic acid and a fulvic acid salt in transplanting rice field weed prevention and control, and rice field yield increasing. According to the invention, fulvic acid and the fulvic acid salt are applied in transplanting rice fields as active components to prevent and control gramineous weeds and broadleaf weeds, shortening rice maturing period, increasing yield factors such as rice plant height, rice spike length, and maturing rate, and increasing rice yield.

Description

technical field [0001] The invention belongs to the technical field of plant protection and fertilizers, and in particular relates to the use of fulvic acid and fulvic acid salts in the control of weeds in transplanted paddy fields and the increase of rice production. Background technique [0002] Rice is the largest food crop in my country. There are many types of weeds in paddy fields, and the types of weeds are different in different regions. There are more than 200 species of weeds in rice areas across the country, of which there are about 40 common and serious weeds. kind. At present, the control of weeds in transplanted rice fields is mainly based on chemical herbicides. For example, benzazine pretilachlor, pyrazole pretilachlor, pretilachlor, etc. can be used to control barnyardgrass, echinacea and other grasses. Undergraduate, sedge and broad-leaved weeds; stem and leaf herbicides can be quinclorac and its intermixtures. Although herbicides are highly efficient and ...
