Problems solved by technology

Therefore, in view of the premature senility of peanuts, a series of water and fertilizer management measures are often used in production to achieve high yields of peanuts, and the investment in production costs is relatively large. Even in years with bad weather, the effect of preventing premature senescence of peanuts is still not optimistic.

Embodiment 1

[0009] Experiments were carried out on the new ordinary peanut line "Hua U632". The specific treatment method was: under field cultivation conditions, sow on June 6 in summer, until 51-53 days after sowing or 24-26 from the first blooming date. At this time, the phenological phase of the peanut plants is the early stage of pod formation, and the exogenous NO sodium nitroprusside solution is used to spray the whole plant once, and the molar concentration of the treatment is 75-125 μmol L -1 , the spraying rate is 50-80 L / mu. The implementation effect is shown in Table 1.

Embodiment 2

[0011] The new ordinary peanut line "Hua U405" was tested, and the specific treatment method was: under field cultivation conditions, sow on June 6 in summer, until 51-53 days after sowing or 24-26 from the first blooming date. At this time, the phenological phase of the peanut plants is the early stage of pod formation, and the exogenous NO sodium nitroprusside solution is used to spray the whole plant once, and the molar concentration of the treatment is 75-125 μmol L -1 , the spraying rate is 50-80 L / mu. The implementation effect is shown in Table 1.

[0012]

[0013] Experiments have shown that: under general cultivation and management conditions, the yield of peanuts treated with exogenous NO sodium nitroprusside solution was higher than that of the control, and the peanut yield was increased by 100 μmol.L -1 The treatment effect is the best, which proves that this new technology using exogenous NO can indeed provide peanut yield, and the production input is low, whic...

Abstract

The invention discloses a method for improving the yield of peanuts and belongs to the technical field of high-yield fertilization of peanuts. According to the technical scheme, the method for improving the yield of peanuts includes the steps that under field production conditions, whole peanut plants in the early stage of pod bearing are sprayed with exogenous NO sodium nitroprusside solution, and the other conditions are the same as those of an ordinary field production management method. The method not only can greatly improve the stress resistance of the peanut plants, but also can lower requirements for water and fertilizer planning and management in the middle and later stages of the peanuts, and therefore the method not only is favorable for preventing premature senescence of the peanuts and improving the yield of the peanuts, but also reduces peanut production cost and provides an important way for promoting peanuts and relieving cultivation.

Description

technical field [0001] The invention belongs to the technical field of high-yield fertilization of peanuts, and in particular relates to a method for increasing peanut yield. Background technique [0002] The yield and quality of peanuts are closely related to the management in the middle and later stages of development. The central task is to ensure that the stems and leaves do not age prematurely and promote the growth of pods under the premise of supplying appropriate amount of fertilizer and water. Peanuts need more water and fertilizer from the pod setting stage to the full fruit stage. If the water and fertilizer supply is insufficient or encounter bad weather, they are prone to premature aging. The specific manifestations are stunted plant growth, poor growth, yellow leaves, reduced photosynthetic capacity, and less nutrients produced. , affecting yield. Therefore, in response to the premature aging of peanuts, a series of water and fertilizer management measures are...
