When is the best time to water peanuts? when is the full bloom of peanuts?

Peanuts are a very common food in our lives. They can be used as casual snacks when chasing soap operas, or as one of the ingredients for making delicious dishes. Many people have eaten this food, but only a few have grown it themselves. There is also a lot of knowledge about peanut planting, such as mastering its watering method is the simplest and most critical.

When is the best time to water peanuts?

1. Dry seedlings

Peanut seedling root development is not perfect, water absorption root is not perfect, if the soil moisture content is relatively large, it will cause the oxygen content in the soil to decrease, and finally lead to yellow seedlings weak. Therefore, in the seedling stage, peanuts can have mouth moisture to ensure the emergence of the situation, can not water on the watering, if it is relatively dry, you can use high spray spray 3-4 hours.

2. Wet flowers

Peanut flowering period is the period of maximum water demand, which is conducive to peanut flowering, if too dry or too much water will be less flowering. At the same time, the watering time should also be noted. The temperature at this time is relatively high. Generally, well water is used for watering. It is relatively cold. It must be watered in the morning or evening. Otherwise, peanuts will be stimulated and will cause rotten needles and rotten fruits.

3. Moistening pods

Peanut in the full fruit maturity period of water demand is not very large, this time is mainly to accumulate dry matter, if you need watering, mainly to raise roots and protect leaves, keep the soil moist can be. This period is the rainy season, we must pay attention to the field do not have water, so as not to affect the yield of peanuts.

When is the peanut bloom?

Peanuts normally bloom from June to August. However, peanuts are one of the foods that can be cooked several times a year. Generally speaking, it takes only about a month from sowing to flowering. When peanut seedlings lateral branches grow 2-4 true leaves, flower buds begin to differentiate. Rosette stage is the period of flower bud differentiation, at this time, most of the differentiated flower buds are effective flowers that can form full pods. A flower bud from the beginning of differentiation to flowering, generally takes 20-30 days, multi-grain type and pearl bean type peanuts shorter, ordinary flower growth.

Management Techniques of Peanut Flowering Stage

1. Cultivation

During the flowering and needling stage of peanuts, deep cultivation is carried out in combination with topdressing, soil cultivation is carried out to meet the needles, the distance between the needles and the soil is shortened, and a loose soil layer is created for the development of the needles. Care should be taken when cultivating the soil to prevent pressing the vines and to prevent loosening or damaging the buried fruit needles. The time is generally controlled in the flowering stage of the plant when the most appropriate soil cultivation. To prosperous long plot union cultivates the soil to carry on the pressure center, presses the peanut tree with the foot, both benefits the fruit needle to enter the soil and prevents prosperous long.

2. Watering and fertilizing

Peanut flowering under the needle stage is the critical period of peanut water demand, drought, waterlogging is very sensitive, this period should be timely watering drought, waterlogging timely drainage. Especially late in anthesis. 30-40 kg of peanut fertilizer is applied in combination with watering mu, foliar topdressing is carried out in full bloom, evenly sprayed, continuously sprayed for 2-3 times, with an interval of 5-7 days.

3. Prevention and treatment of diseases and insects

In the middle and late stages of peanuts, the main prevention measures are leaf spot and brown spot. The control measures can be selected by spraying 800 times solution of 70% thiophanate-methyl WP or 800 times solution of 50% carbendazim WP every 7-10 days for 2-3 times, and good control effect can be obtained. The main pests are cotton bollworms, aphids, grubs, insects and so on

Common Peanut Diseases and Their Control Methods

1. Stem rot

Generally occurs in the seedling stage more often, once infected with its leaves will become dark brown, slowly leaves will become dry rot, and then slowly along the petiole to the whole plant, the longer the disease symptoms will become more and more serious, and finally directly let the leaves die.

Prevention and control methods: The main source of transmission is seeds, seeds bring in germs, and another reason is that the land is too serious to cause the germs left in the last farming to invade our peanuts. Carbendazim solution and thiophanate-methyl solution can be used for spray treatment.

2. Peanut rust

Peanut rust begins at the bottom of the leaf. At the beginning of the disease, yellow spots will appear on the leaves, and then there will be many yellow halo rings on the edges of the leaves. When it is completely cracked, rust powder will be exposed. If the disease is serious, it will dry up and die directly.

Prevention and control methods: in the discovery of the disease should be treated immediately, the use of chlorothalonil solution and triadimefon solution spraying treatment, the effect is very good.

Although peanut is an annual plant, it can reach two or three crops a year. Therefore, if we master its planting technology, we can combine its growth system with crops to make full use of field resources and bring rich economic benefits.
