Peanut seedlings are mainly vegetative growth, and they are also effective in the differentiation of flower buds. The growth characteristics of this period are the slow growth of the aboveground parts and the rapid root extension. The nutrients produced by the plants are mainly used for root development and flower bud formation. Therefore, the central task of seedling management is to control the growth of the above-ground parts in a timely manner on the basis of ensuring Miaoquan Miao Qi, so that the seedlings grow strong but not prosperous, reaching the strong seedlings, thick stems, branches, dense sections, and well-developed root systems. The massive formation of flower buds has created favorable conditions for flowering and blooming. Seed management techniques are as follows:
First, clear seedling seedlings is to pull the soil around the seedlings, so that the two cotyledons exposed the ground, to liberate the first pair of collateral, to play its resulting advantages. Do not damage or knock off the cotyledons, so as not to affect the development of the first pair of lateral branches and the division of secondary branches.
Second, when cultivating weeds and seedlings in combination with Qingchi for cultivator, after the rain break loose pull. After 15-20 days, the first pair of collaterals penetrated into the soil, and the second branch reached the second cultivator when the needles grew. This cultivator had to be interplanted, the ridges were ridged, the soil was raised and the needles were removed, except for the net weeds. . Peanuts are peasants, and after the plants are cleared, the ridges are shallow and the ridges are deep. The mulch covers the peanuts. When weeds appear in the membrane, on the one hand, the membrane covers the soil to make it tightly and airtight. On the other hand, weeds are used to suppress the light and its effects to make it yellow and die. .
Third, pay attention to the control of locusts, spiders, mites and underground pests Aphids, spiders, mites can be used 800 times the omethoate or 10% imidacloprid wettable powder 2500 times spray control. Underground pests can be sprinkled with phoxim and mixed in the surrounding area for prevention and control in the evening.
